Most casino disputes are about money: a withdrawal stuck in pending, winnings voided for a bonus rule, or an account closed after a KYC check. Many get settled at the first level if you complain in writing and stay precise. When they do not, there is an escalation route that costs you nothing, but it only works if you follow the order and keep evidence from day one. This guide walks through each step, what to write, how long each stage takes and what outcome you can realistically expect.
What should you do before filing a formal complaint?
Gather evidence while it is still available. Casinos can change bonus terms, and live chat transcripts are not always emailed to you automatically, so save everything the moment a problem appears.
Then reread the exact terms that applied on the day of the dispute. Many complaints fail because the player missed a rule such as a 5 EUR max bet while wagering, a max cashout on a no-deposit bonus, or a ban on certain games during bonus play. Knowing the clause the casino relies on lets you argue against it precisely, or tells you early that the case is weak.
- Screenshots of your balance, bet history and the withdrawal request with its date and status
- Chat transcripts and emails, including ticket or reference numbers
- The bonus terms and general terms as they read when you played (save a PDF)
- Proof of the KYC documents you sent and the date you sent them
- Transaction records from your bank, card or e-wallet
How do you complain to the casino itself?
Every regulated casino must have an internal complaints procedure, and an ADR body or regulator will normally refuse your case until you have used it. Live chat agents usually cannot reverse decisions, so ask for the formal complaints address and put your complaint in an email.
Keep the message short and factual: your username, the amount, the dates, what happened, which term you think was applied wrongly and what you want (for example, payment of 1,240 EUR in verified winnings). Avoid threats and insults. A calm, documented complaint is taken more seriously and reads better later if an adjudicator reviews it.
- Ask live chat for the official complaints email or form and the expected response time.
- Send one written complaint with dates, amounts, transaction IDs and the outcome you want.
- Attach your evidence or list it clearly so nothing can be called missing.
- Request a final decision letter (often called a deadlock letter) if they reject the complaint.
- Note the date: escalation deadlines run from when you complained or received the final response.
What should a complaint email include?
Structure helps the reader find the facts quickly, whether that reader is a complaints officer or an adjudicator months later. Open with one sentence stating the problem and the amount, then give a short timeline, then the term in dispute and why you think it was applied incorrectly, and finish with the outcome you want and a reasonable deadline for a reply, such as 14 days.
For example: 'On 3 March I requested a withdrawal of 1,240 EUR (ID 88213). My account was fully verified on 1 March. On 6 March the withdrawal was cancelled under clause 12.4 for irregular play. I did not use a bonus and placed standard bets between 0.50 and 2 EUR. Please pay the withdrawal or explain in writing which bets breached clause 12.4.'
Stick to one email thread. Opening new tickets for the same issue scatters your evidence and lets the clock reset.
How long does the casino have to respond?
It depends on the licence. UKGC licensees must resolve complaints within 8 weeks, after which you can go to their ADR provider even without a final answer. MGA licensees must publish their complaint procedure and the ADR entity they use. Under the 2023 Curacao reform, the Curacao Gaming Authority (CGA) adopted a player complaints policy under the LOK that requires licensees to publish a complaint procedure and use a CGA-certified ADR entity.
If the casino's terms give a shorter deadline, it must meet that. Casinos with no clear process, no named ADR body and no response after several weeks are a warning sign in themselves.
Where do you escalate if the casino says no?
Check the footer and the terms for the licence and the named ADR service. UK operators use approved providers such as IBAS or eCOGRA's dispute service. MGA operators name their ADR entity, and you can also report compliance concerns to the MGA's Player Support Unit. CGA licensees must point you to a certified ADR provider.
ADR is free for players. You submit your evidence, the casino replies, and an adjudicator decides whether the operator applied its terms fairly. The adjudicator looks at whether the terms were clear and applied correctly, not at whether the result feels fair to you.
For casinos licensed in jurisdictions with weak oversight, the regulator may not handle individual disputes at all. In that case public mediation on independent review sites is often the only practical lever, which is why the licence matters before you deposit.
Before you file with ADR, check whether the casino's terms set a time limit for escalation. Many schemes expect you to apply within a few months of the final decision letter, and a late case can be refused regardless of its merits.
What about public complaint sites and review portals?
Independent complaint centres on casino review sites mediate thousands of cases a year. They have no legal power, but casinos care about their public record, and many disputes over delayed payouts or unclear KYC demands are settled there within days.
Use them alongside the official route, not instead of it. Post the same facts you sent the casino, answer the mediator's questions quickly and keep the tone neutral. A thread full of anger usually gets closed as unresolvable.
Can a chargeback recover your money?
A chargeback asks your card issuer to reverse a deposit. It is meant for unauthorised transactions or services not provided, not for losing bets you placed yourself. Casinos treat a chargeback as a breach of terms: expect your account to be closed, any balance confiscated and your details possibly shared with other operators.
It can be a reasonable last step when a casino takes deposits but blocks your account and stops answering, but talk to your bank first and expect it to ask what you did to resolve the issue directly. E-wallets and crypto offer little or no chargeback protection.
Which complaints usually succeed, and which do not?
Cases that tend to win involve terms that were unclear, hidden, changed after you accepted them, or applied selectively. Long, unexplained payout delays after full KYC and confiscations based on vague 'irregular play' clauses also often go the player's way.
Cases that usually lose involve a clearly written rule the player broke. A worked example: you take a 100 EUR bonus at 35x, so you need 3,500 EUR in bets, and the terms cap stakes at 5 EUR. If your history shows 30 spins at 10 EUR, an adjudicator will normally side with the casino even if you later won 2,000 EUR. Multiple accounts, using someone else's payment method and false KYC documents also end complaints quickly.
How do you avoid needing a complaint in the first place?
Choose casinos with a licence that has a working ADR route, a visible complaints procedure and a clean public complaint record. CasiScore's table on this page shows casinos with independent safety scores, payout times and terms, which is a quick way to filter out operators with a pattern of unresolved disputes.
Complete KYC before your first withdrawal, read the bonus terms before you opt in, and withdraw winnings instead of leaving large balances on the account. If a dispute is starting to affect your mood or sleep, take a break; no amount is worth that.
Myths vs facts
- Myth: The regulator will step in and order the casino to pay you.
- Fact: Most regulators, including the MGA and the CGA, do not judge individual disputes. They send them to an ADR entity and use complaint data for compliance oversight.
- Myth: Posting a negative review is enough to make a casino pay.
- Fact: Reviews can help, but a documented complaint through the official procedure and ADR is what creates an obligation. Do both if you post publicly.
- Myth: If you won the money, the casino has no right to withhold it.
- Fact: Winnings can be withheld legitimately if you broke a clearly stated term, such as a max bet rule. A complaint only succeeds if the term was unclear or applied wrongly.

- Use public complaint mediation alongside, not instead of, the official route
- Talk to your bank before considering a chargeback
