How to Complain About an Online Casino

To complain about an online casino, write to the casino’s own complaints team first, then take an unresolved complaint to the independent dispute resolution (ADR) body its licence names, and only then to the licensing authority. In Great Britain the operator has 8 weeks to resolve a complaint before you can go to a free ADR provider. Offshore, the Curaçao and Anjouan authorities do not settle individual disputes, so the ADR stage decides most cases.

The order matters because each stage will ask whether you completed the one before. This guide sets out the three stages, what each regulator does and does not do, what to put in your letter, and how long to wait at each step.

Step 1: How do you complain to the casino?

Use the casino’s formal complaints route, not just live chat. Most terms name a complaints email or form and a response time. Write once, clearly, with your account details, what happened, the amount, the dates and what you want. Ask for a reference number and keep every reply, because the next stage will want the full exchange.

1. Find the complaints clause in the terms and conditions and use the address it gives.
2. Put “Formal complaint” and your username in the subject line.
3. Describe the problem in date order: deposit, play, withdrawal request, the casino’s response.
4. State the outcome you want: payment of a named amount, reinstatement of a balance, or an explanation citing a specific clause.
5. Attach evidence: cashier screenshots, transaction IDs, chat transcripts, the terms in force at the time.
6. Note the date sent and the response time the terms promise.

What should the complaint letter include?

A complaint that an adjudicator can decide has five parts: who you are, what happened, which rule applies, what you want, and a deadline. Keep it factual and short. Avoid accusations; you want the casino to answer a specific question, such as which clause it relied on, not to defend itself against a general charge.

Step 2: When can you use an ADR body?

You can use an alternative dispute resolution body once the casino’s own process is finished or has run out of time. In Great Britain that is 8 weeks from when the operator received your complaint, or earlier if it sends a final response, sometimes called a deadlock letter. ADR is free for the player, and once the provider has all the information it has up to 90 days to adjudicate.

ADR bodies decide disputes about money and terms, not about service quality. In Great Britain they will not take complaints about customer service, or about a business refusing a bet or refusing your custom. Every licensed operator must tell you which ADR provider it uses; if it does not, that is a breach in itself and worth raising with the regulator.

What does each regulator do with complaints?

Regulators differ sharply. The UK Gambling Commission records complaints and uses them in compliance work, but does not resolve individual disputes. The MGA’s Player Support Unit stopped ruling on individual disputes on 1 April 2019. The Curaçao Gaming Authority does not mediate individual disputes, and Anjouan routes complaints through the operator’s licence seal.

Step 3: When is it worth going to the regulator?

Go to the regulator when the problem is a licence breach rather than a single disputed payment: an operator that names no ADR body, ignores an ADR decision, uses a seal that does not match the register, or serves a country it should not. Regulators act on patterns and breaches. A clear, dated report with evidence is more useful to them than a long account of one session.

• Great Britain: the Gambling Commission’s contact centre, or its confidential reporting route for illegal gambling.
• Malta: the MGA’s player support contact for licence concerns, and its list of URLs it has no connection with.
• Curaçao: the CGA accepts information at [email protected] for supervision, but does not settle the dispute.
• Anjouan: the complaint form reached through the operator’s seal.

What if the casino has no valid licence?

Then there is no ADR body and no regulator that will act on your behalf, and your options are your payment provider, a report to the authorities in your own country, and in rare cases a court. Check the licence before you rely on any route: our licence check guide shows how, and our page on unlicensed casinos explains what changes when the check fails.

If you paid by card or e-wallet, a dispute with your provider can still work within its time limits; the chargebacks and crypto guide covers the rules. A crypto transfer, once confirmed on the blockchain, has no chargeback mechanism, which is the main reason to keep balances small at offshore casinos.

How long does the whole process take?

Expect weeks, not days. A typical licensed route takes up to 8 weeks with the operator and up to 90 days at ADR after the provider has everything it needs. Offshore routes vary: Anjouan gives the operator 30 days to respond. Keep a single file with every date so you can show you met each deadline.

Which complaints usually succeed?

Complaints succeed when the facts are documented and the casino cannot point to a clear clause. A withdrawal cancelled without reason, a balance removed under a rule that was not in the terms, or a document request that keeps changing are strong cases. Complaints based on bad luck, game results that feel unfair, or terms you accepted but did not read are weak.

Bonus disputes are the grey zone. If the casino cites a maximum bet or game restriction and your history shows a breach, an adjudicator will usually side with the terms. If the clause is vague, such as “irregular play”, the casino has to show what you did. Our page on bonus terms to avoid lists the clauses that cause most disputes, and our withdrawal delays page shows which delays are normal.

What if the casino closes during your complaint?

Keep going, but change the address. The company named in the terms is still responsible after its website goes dark, so send your complaint to its registered address and any email it uses for other brands. If the casino named an ADR body, that body may still accept the case. Note the closure date and attach a screenshot of the closure page.

A closure also starts the clock on your payment provider’s dispute window, so contact your card issuer or e-wallet early rather than waiting for the ADR outcome. Our closed casinos page explains what part of a balance is realistically recoverable, and the casinos to avoid list shows which brands we have already confirmed closed.

Common mistakes that weaken a complaint

• Skipping the operator stage. ADR bodies send you back if the casino never had a formal chance to answer.
• Complaining in chat only. Chat transcripts can vanish; email or a form gives you a dated record.
• Playing on after the dispute starts. New bets on the disputed balance muddy what you are claiming.
• Opening a second account. It breaches almost every casino’s terms and hands the casino a reason to refuse payment.
• Missing a deadline. Anjouan requires game-outcome disputes within 14 days; card disputes have their own limits.

Should you post your complaint publicly?

A public post can bring a response, but it can also make things harder. Keep the formal route going in parallel, stick to facts you can prove, and avoid words such as “scam” or “fraud” unless a regulator or court has used them: a casino can treat accusations as a breach of its terms, and in some countries as defamation.

Private complaint platforms run by review sites sometimes mediate between players and casinos. They are not regulators and their decisions do not bind anyone, but some casinos respond to them. If you use one, give it the same five-part letter and keep your ADR deadline in view.
