How to Complain About a Casino: Steps, Evidence and Who to Ask
A casino did not pay, closed your account or ignored you? Plain steps: keep proof, write to support, go to the regulator, and use a free mediator. We do not take complaints ourselves.

Most problems with a casino are about money: a withdrawal that does not arrive, a bonus that was taken away, or an account that was closed after a win. This guide shows the steps in the order that works best, and what each helper can and cannot do. It is general information, not legal advice. CasinoRadius does not take or handle complaints. We are a review site, not a regulator and not a court.
Before you write anything: keep proof
Start a folder (on your phone or computer) and keep:
- screenshots of your balance, deposits, withdrawal requests and their status, with the date and time visible
- the chat transcripts and e-mails with support, and any ticket numbers
- the casino's terms and bonus terms as they were when you played (take a screenshot or save the page)
- the exact amounts, dates and the payment method you used
Do not delete the account. Do not open a second account. Do not use a VPN to hide your country, because many casinos treat it as a breach of the terms and can use it to void winnings (NV Casino's terms, for example, say so). Read the bonus terms again: wagering, maximum bet and excluded games are the most common reasons for a refusal.
Step 1: write to the casino support
Use the live chat or the e-mail address of the support team, and ask for a ticket number. Be short, polite and exact. Say what you want and by when. Keep every answer. A message you can copy is at the end of this guide.
Wait for the time the casino itself states in its terms. If no time is stated, give it about 7 days. A complaint to anyone else is easier to handle when you can show that you tried first. The UK Gambling Commission, for example, says you should complain to the gambling business first.
Step 2: escalate inside the casino
Look in the terms for a complaints or disputes address, or a "dispute resolution" section. Some casinos name an outside dispute-resolution body there. Write to that address with your ticket number and the facts, and say that you are asking for a final decision in writing.
Step 3: the regulator named in the licence
The casino's footer names a regulator. Check what that regulator actually does with complaints. We read these pages on 6 November 2026:
- United Kingdom (UK Gambling Commission): the Commission says you should first complain to the business. It does not resolve or make decisions on complaints about gambling transactions itself.
- Kahnawake Gaming Commission: you can write to it by e-mail or an online form. It says it will "facilitate appropriate solutions" between you and the operator. It may drop a complaint that was already handled by a recognised organisation, aired on a public forum or sent to the media.
- Isle of Man (Gambling Supervision Commission): complain to the operator first, then to the Commission with the correspondence and the terms you think were broken. It will not investigate complaints about operators it does not license, and it will not act until the operator's own process has finished.
- Curacao (Curacao Gaming Authority): its site lists a Player Complaints Policy and an alternative dispute resolution (ADR) policy. We saw the titles but did not read the content, so we cannot tell you how a complaint works in practice. Trade guides say operators must use an approved dispute-resolution provider. We could not confirm that on the regulator's own pages.
- Anjouan: the regulator's page links to a player complaint process. We did not read it. Remember that the status of this regulator is disputed (see our guide casino licences compared).
- Malta: we could not open the regulator's site. Secondary sources say licensees must refer players to an ADR body. Check the regulator's own page.
None of these pages promised that a regulator will get your money back. Many do not decide individual disputes at all.
Step 4: a free mediator
Some review sites run a free mediation service. AskGamblers' page, for example, says you must first try the casino yourself and have an account, then fill in a form with the facts and evidence. It says you hear back within 2 working days, that the team then contacts the casino, and that you can reopen an unresolved case twice. It also says that if you broke the casino's terms you will be advised to contact the licensing authority, and it asks you not to discuss the case publicly until it is closed.
A mediator can ask a casino to answer. It cannot force a payment. Casinos that are not on the site's list may not take part. Remember that such sites also earn money from casinos, as we do.
If the casino is not licensed in your country
A licence from one country does not make a casino legal in another. Authorities in some countries act against unauthorised online gambling (the Croatian Tax Administration, for example, has a page on it). If the casino is not authorised where you live, you may have fewer options, and a regulator abroad may say it is not responsible. For a large amount, speak to a lawyer in your own country.
Warning signs
- The casino asks you to pay a "fee", "tax" or "verification deposit" before it releases your winnings.
- It changes the terms after your win, or quotes a rule you cannot find in the terms.
- Someone contacts you offering to "recover your money" for an advance fee. Do not pay.
- Support stops answering after you ask about a withdrawal.
A message you can copy
Hello. My account is [username or e-mail]. On [date] I asked to withdraw [amount and currency] with [payment method] (reference [number]). After [number] days the status is still [pending / declined]. I have sent the documents you asked for on [date]. Please tell me in writing the exact reason and the date the money will arrive, and please give me a ticket number. If I have no answer by [date, 7 days from today], I will contact the regulator named in your licence.
In short
- Keep proof from the first day. Do not delete the account.
- Write to support first, in writing, and ask for a ticket number.
- Escalate inside the casino, then go to the regulator named in the licence. Know what that regulator really does.
- A free mediator can ask the casino to reply. It cannot force a payment.
- Never pay a fee to get your winnings, and be careful with "recovery" offers.
- Set limits before you play, so that a problem stays small.
Play with care
Gambling is for adults aged 18 and over. It is entertainment, not a way to earn money, and it can be addictive. Play only with money you can afford to lose. Set a deposit limit and a time limit before you start, and stop when you reach them. If gambling stops being fun, talk to someone you trust. Organisations such as GambleAware offer free, confidential help (GambleAware serves people in Great Britain, so look for a service in your own country). Gambling rules and what is allowed differ by country. Check the law where you live before you play. This guide is general information, not legal advice.
