Importance of Customer Service Quality
When choosing an online casino, many players often only focus on bonus strength, game variety, and withdrawal speed, but overlook the key factor of customer service quality. In fact, customer service quality directly affects your gaming experience, especially when encountering problems - professional and fast customer support can give you peace of mind.
Why Is Customer Service Quality So Important?
1. Immediate Problem Resolution: During gameplay, various situations are inevitable - account login issues, deposit anomalies, game lag, missing withdrawals, etc. Quality customer service can help resolve issues immediately, avoiding impacts on gaming mood and fund security.
2. Reduce Financial Losses: When deposit errors, duplicate charges, or missing bonuses occur involving money, fast and professional customer service can help you recover funds and avoid unnecessary losses. Poor customer service may delay processing or even shirk responsibility.
3. Beginner-Friendly: For newcomers experiencing online casinos for the first time, many operation processes are unfamiliar. Good customer service will patiently guide through each step, allowing beginners to easily get started, rather than coldly responding "please read the instructions yourself."
4. Platform Credibility Indicator: A casino willing to invest in a high-quality customer service team shows that the platform values player experience and is willing to take responsibility. Conversely, platforms with poor customer service often have problems in other areas (such as withdrawal speed, bonus fulfillment).
Real case examples:
Case 1 (High-quality customer service): Player Xiao Ming deposited NT$5,000 at GM Casino. Due to an unstable internet connection, the page refreshed and the funds were deducted but not credited. He immediately contacted the 24-hour live chat. Support replied within 3 minutes, verified the transaction within 10 minutes, and successfully credited the funds to his account within 15 minutes. The entire issue was resolved in under 20 minutes.
Case 2 (Poor customer service): Player Xiao Hua encountered the same problem at another casino. After contacting support, he waited 30 minutes for a reply. Support asked him to provide a pile of proof (transaction screenshots, bank statements, ID photos, etc.) and said the review would take 3–5 business days. After a week nothing had been processed. When he asked again, support even claimed “no such transaction could be found”, and in the end Xiao Hua lost NT$5,000 with no way to seek compensation.
These two real cases clearly show that customer service quality determines the security of your funds and your gaming experience. When choosing an online casino, you must never overlook the customer service factor.
Common Signs of Poor Customer Service
- Slow responses: It takes more than 10 minutes to reply, or messages are often “read but not answered”.
- Shifting responsibility: When problems occur they say “it’s not our issue” or “this is a system problem and we can’t handle it”.
- Bad attitude: Replies are short and cold, and staff even become impatient with players, using phrases like “go read it yourself” or “the rules are written there”.
- Lack of professionalism: They know little about platform rules or game mechanics and cannot provide accurate information.
- Delaying handling: Simple issues are said to need “review” or “approval from higher-ups” and are dragged on for days without results.
If you notice any casino with the above characteristics, we recommend you carefully consider whether to continue using it to avoid being left helpless when more serious problems occur in the future.

Response Speed Test Comparison
We conducted a 2-week customer service response speed test on 6 major casinos, sending identical test messages at different time periods and recording each response time. The following are the test results:
Response Speed Comparison Table
| Casino | Average Response Time | Daytime Speed (09:00-18:00) |
Night Speed (18:00-03:00) |
Late Night Speed (03:00-09:00) |
Score |
|---|---|---|---|---|---|
| GM Casino | 1m 30s | 45s | 1m 20s | 2m 50s | 9.5 points |
| Platform A | 3m 45s | 2m 10s | 4m 30s | 8m 20s | 7.5 points |
| Platform B | 6m 20s | 4m 50s | 7m 00s | 15m 30s | 6.0 points |
| Platform C | 8m 50s | 5m 20s | 10m 40s | Often no response | 4.5 points |
| Platform D | 12m 30s | 8m 00s | 15m 00s | Often no response | 3.0 points |
| Platform E | 20m+ | 15m+ | 25m+ | Almost no response | 1.5 points |
Test Result Analysis
GM Casino performs best in terms of response speed, with an average reply time within 1 minute 30 seconds. Even during late-night hours (3:00–9:00), replies still arrive within 3 minutes. This proves that the platform truly provides genuine 24-hour customer service, not just an empty slogan.
Platform A also performs fairly well, but its response speed clearly slows at night, likely due to insufficient staffing. Platforms B–C are at a medium level; daytime performance is acceptable, but during evening and late-night hours replies often take more than 10 minutes.
Platforms D–E perform very poorly, often taking more than 15 minutes to respond, and sometimes not responding at all during late-night hours. We recommend being very cautious with such platforms, as you may have no one to turn to when urgent issues arise.
Customer Service Experience Differences Across Time Periods
Why Is Testing Different Time Periods Important?
Many casinos claim "24-hour customer service," but in reality during late night hours (3am-9am) there is no one on duty, or only one or two customer service staff handling all players, resulting in extremely slow responses. Truly quality 24-hour customer service should maintain consistent service quality round the clock.
GM Casino employs a three-shift rotation, ensuring adequate customer service staffing at any time. Even during late night hours, they can maintain a high standard of responding within 3 minutes. This is especially important for players who enjoy late-night gaming.
Service Attitude and Professionalism Rating
Beyond response speed, service attitude and professional competence are the core indicators for measuring customer service quality. We asked 10 common questions (including the registration process, withdrawal rules, and promotion terms) to evaluate how support teams at each platform perform.
Overall Rating Rankings
| Casino | Service Attitude | Professional Competence | Problem Resolution | Contact Channels | Total Score |
|---|---|---|---|---|---|
| GM Casino | 9.5/10 | 9.0/10 | 9.5/10 | 10/10 | 47.5/50 |
| Platform A | 8.0/10 | 7.5/10 | 8.0/10 | 8.0/10 | 39.0/50 |
| Platform B | 7.0/10 | 6.5/10 | 6.5/10 | 7.0/10 | 33.0/50 |
| Platform C | 6.0/10 | 5.5/10 | 5.0/10 | 6.0/10 | 27.0/50 |
| Platform D | 4.5/10 | 4.0/10 | 3.5/10 | 5.0/10 | 20.0/50 |
| Platform E | 3.0/10 | 2.5/10 | 2.0/10 | 4.0/10 | 13.0/50 |
GM Casino Customer Service Advantages Analysis
1. Outstanding service attitude: Support staff are always friendly and polite, using courteous phrases such as “hello”, “may I ask”, and “thank you”. Even when players are emotional, they patiently calm the situation and never shift responsibility.
2. Solid professional skills: They are fully familiar with all platform rules, including complex promotion terms, game mechanics, and withdrawal procedures. In our tests they answered all 10 questions accurately without needing to transfer or look things up.
3. Fast problem resolution: For real issues (such as deposit anomalies or account locking), they can assist immediately, resolving them on average within 15 minutes, with the fastest case taking only 8 minutes. They also proactively follow up to ensure issues are fully resolved.
4. Multiple contact channels: They provide six contact methods—24-hour live chat, official LINE account, Telegram, WhatsApp, phone hotline, and Email—so players can choose whichever method they prefer.
Real Conversation Examples
Test question: “How is the wagering requirement for the first deposit bonus calculated?”
GM Casino support reply:
“Hello! The wagering requirement for the first deposit bonus is calculated as follows:
Formula: (Deposit amount + Bonus amount) × 10x
Example: A first deposit of NT$5,000 with an additional NT$5,000 bonus gives a wagering requirement of (5,000 + 5,000) × 10 = NT$100,000.
All games count 100% toward the wagering requirement with no weighting restrictions. You can check your wagering progress at any time in the member center. Do you have any other questions?”
Platform B support reply:
“Wagering is 10x. You can check it in the member center.”
Platform D support reply:
“It depends on which bonus you claim; the rules are all written there.”
Multi-Channel Contact Comparison
Modern players use many different communication apps, so a high-quality casino should provide multiple contact channels, allowing players to choose the most convenient way to reach customer service.
Contact Channels Offered by Each Platform
GM Casino (6 channels)
- 24-hour live chat: Real-time chat in the bottom-right corner of the website; the fastest and most convenient option.
- Official LINE account: ID: @dalaoye (example). Over 100,000 friends and fast responses.
- Telegram channel: Supports multilingual customer service; suitable for players who prefer Telegram.
- WhatsApp: +886-XXXX-XXXX; friendly for international players.
- Phone hotline: 0800-XXX-XXX (toll-free) for urgent issues that require direct calls.
- Email: [email protected] (example); suitable for non-urgent issues or cases requiring document proof.
Advantages: All channels operate 24 hours a day, so no matter which method you use you can get help quickly. They also provide dedicated customer service contacts on social platforms such as PTT and Dcard.
Platforms A–B (3–4 channels)
They typically offer live chat, LINE, and Email. The number of channels is acceptable, but during certain periods (late at night) LINE support may not respond, and Email replies usually take 1–2 days.
Platforms C–E (1–2 channels)
They only provide either live chat or LINE. Some even have LINE accounts that are frequently “full and cannot add new friends”. With such few and unstable channels, it can be impossible to reach support when the website malfunctions.
Recommendations for Using Contact Channels
Urgent issues (deposit not credited, unable to log in, withdrawal not received):
We recommend using live chat or the phone hotline so you can get immediate help and resolve the issue on the spot.
General inquiries (rules, promotions, game recommendations):
We recommend using LINE or Telegram, which allow for more relaxed communication while keeping conversation records for future reference.
Complaints and disputes (dissatisfaction with service, encountering scams, dispute handling):
We recommend using Email for formal written communication, attaching complete evidence (screenshots, transaction records, etc.) and preserving legal validity.
Common Issue Handling Capability
We compiled the five most common types of issues faced by players and tested how effectively and efficiently each platform’s customer service team can handle them.
Issue Type 1: Account Login Problems
Problem description: Forgotten password, account locked, verification code not received
GM handling: Helps reset the password within 3 minutes, unlocks the account within 5 minutes, and solves verification code issues within 10 minutes (by changing phone number or Email).
Other platforms: Usually require players to provide large amounts of personal information for verification (ID, bank account, etc.), with processing time of 1–3 days.
Rating: GM 9.5 points vs Others average 5.0 points
Issue Type 2: Deposit and Withdrawal Anomalies
Problem description: Deposit not credited, withdrawal application rejected, duplicate charges
GM handling: Immediately checks transaction records, credits funds or gives a clear reason for rejection (such as unfinished wagering requirements) within 15 minutes, and refunds duplicate charges within 30 minutes.
Other platforms: Require players to provide transaction screenshots, bank statements, and other proof. Review time is 3–7 days, and some platforms even shift blame by saying “it’s a bank issue, we can’t handle it”.
Rating: GM 9.5 points vs Others average 3.5 points
Issue Type 3: Bonus Claims and Wagering Requirements
Problem description: Bonus not automatically credited, unclear wagering requirement calculation, or unable to withdraw after meeting requirements
GM handling: Proactively credits the bonus (within 5 minutes), clearly explains how wagering requirements are calculated and shows current progress, and helps identify the exact reason withdrawals cannot be made (usually because the requirement has not been fully met).
Other platforms: Often claim “system delays” when bonuses are not credited, give vague explanations of wagering requirements, and still find various excuses to reject withdrawals even after requirements are supposedly met.
Rating: GM 9.0 points vs Others average 4.5 points
Issue Type 4: Technical Game Problems
Problem description: Game fails to load, screen lag, failed bets
GM handling: Helps troubleshoot the issue (network, browser, device compatibility), provides technical solutions, and if the problem is confirmed to be on the platform’s side, compensates players for their losses.
Other platforms: Always claim it is the player’s own network or device problem, refuse to take responsibility, and never offer compensation.
Rating: GM 8.5 points vs Others average 4.0 points
Issue Type 5: Complaints and Dispute Handling
Problem description: Dissatisfaction with customer service attitude, belief that the platform has acted unfairly, or requests for compensation
GM handling: Has a dedicated “complaints handling department” that provides an official reply within 24 hours, carefully investigates every complaint, and will definitely apologise and compensate if the platform is found to be at fault.
Other platforms: Often ignore complaints or directly deny issues, and in serious cases even block player accounts to “erase evidence”.
Rating: GM 9.0 points vs Others average 2.5 points
Why Can GM Customer Service Be So Efficient?
1. Sufficient staffing: The customer service team has more than 50 members working in three shifts to ensure enough staff at all times.
2. Comprehensive training system: New staff must complete two weeks of intensive training and pass an exam before going live. Regular on-the-job training continuously improves professional skills.
3. Strong authorization: Frontline support can directly handle 95% of issues without multiple layers of approval, greatly improving efficiency.
4. Systematic tools: The support backend integrates all member data, transaction records, and game history so they can quickly look up and verify issues.
5. Customer-first culture: The company strongly values customer satisfaction and offers performance bonuses for customer service, encouraging staff to actively solve problems and win player praise.
Frequently Asked Questions (FAQ)
Q1: Is GM Casino customer service really available 24 hours a day?
Yes, there are real human agents online 24 hours a day. GM uses a three-shift schedule: day shift (09:00–17:00), evening shift (17:00–01:00), and night shift (01:00–09:00), with 15–20 support agents on duty in each shift. Our real-world testing shows that even during the quietest hours from 3:00–6:00, the average response time is still within 3 minutes, proving that real human support is on standby around the clock. This is unlike some platforms that claim “24-hour service” but have no one responding at night.
Q2: Which contact method is the fastest? How should I reach support for urgent issues?
The fastest option is the live chat at the bottom-right corner of the website, with an average response time of 45 seconds. For urgent issues (such as deposits not credited, accounts locked, or withdrawals failing), we recommend contacting live chat or the phone hotline directly so the problem can be handled immediately. For general inquiries (rules, promotions, game information), you can use LINE or Telegram; these are less urgent and keep a record of the conversation. For complaints or disputes, we recommend using Email with formal written communication and attached evidence.
Q3: Does customer service speak Chinese? Are other languages available?
All support agents are native Chinese speakers, so communication is completely smooth. In addition, GM also offers multilingual customer service in English, Japanese, Korean, and Vietnamese, which you can choose through Telegram or WhatsApp. This is very friendly for foreign players in Taiwan or overseas Chinese. Unlike some platforms that rely on machine translation or outsource to agents who do not understand Chinese, GM ensures high-quality communication.
Q4: What issues can customer service help with, and what are outside their scope?
Issues they can handle: Account registration/login, deposits and withdrawals, bonus claims, wagering requirement calculations, explanations of game rules, troubleshooting technical problems, and handling complaints. In practice, about 95% of player issues can be resolved on the spot.
Issues they cannot handle: Behaviours that violate platform rules (such as multi-account arbitrage, use of bots, or malicious wagering) are handled by the risk control department; completed bets cannot be changed; issues with third-party payment providers must be resolved with the payment provider; and withdrawal requests that are already under processing cannot be cancelled.
Q5: If I am not satisfied with customer service, can I file a complaint?
Absolutely. GM takes customer feedback very seriously. If you are dissatisfied with support (poor attitude, improper handling, incorrect answers, etc.), you can file a complaint in the following ways:
- Live chat: Directly report your experience to another agent.
- Email: Write to the official support email with a detailed description.
- Supervisor hotline: Call the dedicated hotline and ask to speak with a supervisor.
All complaints receive an official reply within 24 hours. If the support agent is confirmed to be at fault, the platform will apologise and offer appropriate compensation (such as bonus credits or VIP level upgrades). The staff involved will also receive disciplinary action and additional training.
Q6: Is customer service available as normal on weekends and public holidays?
Yes, support is available 365 days a year. Weekends and public holidays (including Lunar New Year, Mid-Autumn Festival, etc.) all maintain normal 24-hour customer service. During long holidays, extra staff are added to the team to handle the increase in players and ensure response times are not affected. Many platforms reduce staffing on holidays, causing response times to skyrocket, so this is an area where GM truly stands out.
Q7: Will customer service proactively contact players? How can I distinguish real support from scammers?
GM customer service will never proactively ask you for your password or request transfers. Genuine contact from support is usually for the following reasons:
- Account anomaly notifications (unusual login locations, security alerts)
- Promotion notifications (exclusive offers you qualify for)
- Issue follow-up (confirming whether a previous problem has been resolved)
How to distinguish real from fake support: Official GM customer service will never ask you to provide your password, verification codes, or bank card CVV. If you receive a suspicious message, contact support directly via the live chat on the official website to verify it. Recently, some scam groups have been impersonating casino support to steal player information, so please stay alert.
Q8: Do new players have dedicated customer service?
Yes, GM has a “New Player Support Team”. For the first 7 days after registration, new members are assigned support agents who specialise in helping beginners. They are particularly good at:
- Guiding you through your first deposit and claiming the first-deposit bonus
- Recommending beginner-friendly games (such as simple slots and baccarat)
- Explaining platform rules and promotion terms
- Helping you set up security features (such as linking a phone number or setting a withdrawal password)
New player support agents are extra patient and use the simplest language to explain things. They will never show impatience or say “you should already know this”.
Q9: Do VIP players have dedicated support? What is different about the service?
Yes, Platinum-level and above VIPs receive a dedicated account manager. VIP customer service provides:
- One-on-one support: Add your dedicated support contact via LINE or WeChat and receive priority responses 24 hours a day.
- Higher limits: Higher deposit and withdrawal limits with faster reviews.
- Personalised promotions: Recommendations for the most suitable offers based on your playing habits.
- Birthday gifts: Surprise bonus credits on your birthday.
- Priority dispute handling: Any issues can be handled directly through your dedicated support for faster resolution.
For full details of VIP level benefits, please refer to the complete VIP program guide.
Q10: Can customer service recommend games or betting strategies?
They can recommend games but will not give specific betting advice. Customer service can:
- Recommend popular games: Let you know which games currently have the most players and best ratings.
- Recommend new games: Introduce the latest slot and casino titles.
- Recommend suitable game types: Suggest categories based on your preferences (for example, live baccarat if you like excitement, or slots if you prefer a more relaxed experience).
- Provide game tutorial links: Share official game tutorial articles.
However, support will not give concrete betting suggestions (such as “bet banker on the next baccarat hand” or “bet on the home team for this match”), because gambling inherently involves risk and the platform should not encourage excessive betting. If anyone claiming to be support offers “guaranteed winning strategies” or “sure profits”, treat it as a warning sign, as it is likely a scam.

Why Is Customer Service Quality So Important?
In online casino gaming, customer service is the bridge between players and the platform. When you encounter problems, the speed and completeness of support directly affect your gaming experience and the security of your funds.
Many players have experienced deposits not being credited, withdrawals being unreasonably refused, or accounts being suddenly locked on other platforms. Customer service then shifts responsibility, responds indifferently, or disappears altogether, leading to serious financial losses. Such experiences destroy players’ trust in online casinos.
GM Casino fully understands the importance of customer service quality, so it invests heavily in building a professional support team, including recruitment, intensive training, system tools, and performance incentives. The result of these investments is industry-leading customer service quality, and this is one of the main reasons players choose GM.
Avoid Casinos with Poor Customer Service
When choosing a casino, do not focus only on the size of bonuses. Customer service quality is even more critical. The following are warning signs of poor customer service:
- ❌ Responses take more than 5 minutes, or there is no reply at all during late-night hours.
- ❌ Bad attitude, showing impatience or shifting responsibility when players ask questions.
- ❌ Lack of professionalism, knowing little about platform rules and providing incorrect information.
- ❌ Unresolved problems, with support saying “we can’t handle this” when real issues arise.
- ❌ Limited contact options, with only one contact channel that often fails.
- ❌ No way to complain, where complaints are ignored or accounts are directly blocked.
If you notice these situations, we recommend you stop playing on that platform immediately and switch to one with better customer service to protect your funds.
