There are many reasons why a player may wish to make a gambling complaint against an online casino. At the extreme end of the scale, a player may want to make public a case they suspect of online fraud. Sometimes, a player could feel justifiably cheated out of their winnings. More often than not, however, a complaint is for the poor service they have received from a particular online gambling venue. This article covers the procedure you need to take to start the casino complaint process.

RouletteUK — Refund declined

I have played at the casino in question several times, having little luck.

Given my gaming activity, the VIP Manager (Bella) appears via email offering me a 120% deposit bonus, with no withdrawal limits and with a maximum bet of €5. I accept this bonus and then proceed to complete the wagering. I ended up winning a sum of around €2000, which I increased with bets exceeding €5 (the wager had now ended) and reaching an amount of €3400. When I finally make the withdrawal, the winnings are confiscated and I am only refunded the initial deposit. According to them, I had broken the maximum bet rule, but this was only done after completing the rollover.

I'll explain the situation step by step.

1) I contact the VIP Manager to understand the reason for the confiscation, and he explains to me that I violated the rules on the maximum bet. However, it refers not to the bonus he offered me, but to an alleged LV 3 cashback bonus. I thought he was referring to an old cashback bonus where actually, thinking about it, I could have violated the maximum bet, but I didn't understand how it could be linked to the bonus offered to me by the VIP manager and which originated the winnings.

I then ask for explanations in chat, from a very kind agent, who explains the matter to me.

2) The chat agent explains to me that, while I was playing with my winnings (by now the wager was completed, so I was able to raise the bet), I received a cashback bonus (which I didn't notice!) credited automatically, and for this specific bonus I violated the max bet rule. I explain to him that I didn't really notice this bonus, and that it wasn't right that I was punished for a violation that wasn't done voluntarily.

The agent appears to be cooperative and invites me to send a transcript of the chat with him to my VIP manager, which he would also do with the department that deals with payment.

3) I then write to the VIP manager, who however continues to deny me the winnings, referring to the violation of the terms on the maximum bet. I explain to him that I didn't notice this automatically credited bonus, and that it's not right to confiscate all my winnings for an alleged violation made on a bonus that I didn't request (Could I ever risk €3000 in winnings for a €50 bonus? Impossible!). At this point the VIP manager claims that I would have also violated the 120% credited bonus, but I think it is an excuse invented to deny me the winnings at all costs (He had not previously mentioned this alleged violation). Too bad I can only see the last 50 transactions and can't prove it.

4) Next, I receive the same email in three different languages saying that I would receive my winnings but to pay attention to the terms of the bonus next time. So I rejoice and think it's all over. I ask the VIP manager for confirmation, who tells me that the email was sent by mistake.

Even an email in 3 different languages? I feel really cheated!

The email specifically says that it is possible to receive winnings even if you violate the rules. So why isn't I allowed this opportunity? I have made many deposits on their site, my losses far exceed my wins and I have never misbehaved. I feel so frustrated and treated unfairly.

Thank you for your help.

Step 1: Contact the Casinos Customer Support Team

The first thing you must do in the process of making a complaint is to contact customer support. Now you may feel that this is a waste of time, but all the same, you must go through the process for two important reasons. First, the casino will tell you if you are in violation of any of its policies. If you are (knowingly or unknowingly) in violation, it will be difficult for you to advance your complaint further. 

Now one wants to go through the time-consuming reading of a casino’s terms and conditions before jumping on some exciting casino games. We get that. But failure to do so could leave you disappointed if things don’t work as you expect, particularly concerning casino bonuses and promotions. 

Secondly, the first thing any third-party agency will ask before they assist with your complaint is whether you have spoken to the casino’s support team and what the outcome was. Failure to answer this question positively and provide details will ultimately mean your complaint will not go further.

Step 2: Lodge a Formal Complaint with the Licensing Authority

All legitimate online casinos are affiliated with a gambling license authority. If the casino you want to use does not have a casino license, avoid them at all costs. Casinos with a license from a reputable agency offer a degree of player protection and redress for complaints. But some are better than others. Online casinos licensed in south American jurisdictions like Curacao and Costa Rica offer very little player protection. They are unlikely to listen to your complaint. For this reason, it is always better to play at a casino that is licensed and regulated by regulators such as the United Kingdom Gambling Commission (UKGC), Malta Gaming Authority (MGA), or one of many other European agencies. - Resolver can help you with submitting a complaint against casino in UK.

The footer of every online casino is where you can find out which regulator the casino is licensed with, usually. Clicking on the link here will often take you directly to the regulator’s website. From there, you can navigate to the section relating to casino complaints. Be aware, however, that this process could take months. And also, regulators will often only take action when they receive several similar complaints about a particular online gambling establishment.

Step 3: Casino Watchdogs

If there is no legal route available, there is also a third option. This is to submit a grievance through a trusted casino review company. Although they have no legal authority, top review websites can blacklist a casino and provide players with the ability to make their complaints public knowledge. This is a potent weapon against fraudulent and unethical gambling operators. The best casino review companies have many thousands of users and subscribers. It means you can get the word out about dishonest and unethical behavior fast. 

  • - A new player in the market, but already a fairly successful one. Due to established good relations with various casino brands, we are able to reach out to them to mediate any conflicts and complaints. And be heard - we have solved 100+ complaints so far and counting.

  • - An established platform with 2000 reviewed casinos. And a transparent complaint mechanism that has helped almost 15000 gamblers to receive their winnings. Takes from a week to a month to resolve a complaint. 

  • - An independent review website with an established complaint mechanism. Less transparent than such at AskGamblers, but with 4000 casinos present, it’s more likely you’ll find the needed one here. On average it takes 24 hours to accept a complaint and 21 day to resolve it.

  • - accepts complaints without making them public like the two sites above. And employs a dedicated team for mediation. It usually takes up to 2 working days to accept a complaint. But the problem is the limited number (around 300) of casinos supported. 

  • - A famous gambling review website acting as an Alternative Dispute Resolution service. Fairly active and accepts complaints on several hundreds of casinos. However, it has fairly strict guidelines leading to players’ complaints frequently being denied. And is often unable to help due to casinos’ unwillingness to cooperate. Successful cases are usually resolved within a week or two. 

Informing the casino you are using that you intend to air your grievances public can, in some instances, help to resolve an issue. Blacklisting and bad player reviews, after all, have a significant impact on a casino’s ability to operate profitably.
