How to complain about an online casino
Disputes with casinos usually involve withheld winnings, delayed withdrawals, voided bonuses or closed accounts. Knowing how to complain effectively — and to whom — makes a real difference to the outcome. This page sets out the general route for complaints. Note that this site is not the operator and cannot resolve complaints about player accounts; we can only explain the process.
Step 1: complain to the operator in writing
Start with the operator's customer support, then its formal complaints procedure, which is usually described in the terms. Put your complaint in writing (email or the complaints form rather than only live chat) and include your username, the dates, amounts, transaction references and the outcome you are asking for. Keep it factual. Save every reply. Most licences require the operator to respond within a set time.
Step 2: ask for the reason and the clause
If the operator refuses, ask which specific term it is relying on. Many disputes concern bonus rules — maximum bet, restricted games — or verification. Compare the clause with what happened, using our bonus terms explainer or the withdrawal guide. Sometimes the answer reveals a missing document that can simply be supplied.
Step 3: dispute resolution through ADR
If the operator's final answer does not settle the matter, many regulators require licensed operators to be members of an alternative dispute resolution (ADR) service. An ADR body is an independent mediator that reviews the case, often free of charge for players. The operator's terms should name its ADR provider. ADR decisions may or may not be binding, depending on the scheme.
Step 4: the regulator
Regulators generally do not act as a court for individual disputes, but they want to know when operators break licence conditions. A complaint to the regulator can lead to an investigation of the operator's practices. Check the regulator's website for its complaint form and what it does and does not handle.
If the operator is licensed abroad
With an operator licensed in another country, your route runs through that foreign regulator and the ADR scheme it requires — not through your own country's authorities. Some foreign regulators offer limited complaint handling. If the operator holds no verifiable licence at all, there may be no regulator to turn to; that is the risk to weigh before depositing. In Belgium, for example, the Kansspelcommissie does not mediate player–operator disputes; for unlicensed sites it can only add them to its list of blocked sites.
Payment disputes and legal advice
If you paid by card, your bank may be able to help in specific cases such as unauthorised payments, but chargebacks for gambling losses are rarely accepted. For larger amounts, a consumer organisation or a lawyer can assess your position. Be wary of "recovery services" that promise to get your money back for an upfront fee — these are often scams.
A template for your complaint
Subject: formal complaint, account [username]. Describe what happened in date order, list the amounts and references, name the rule you believe was applied wrongly, and state what you want: payment, an explanation or reinstatement. Ask for a reply within the period stated in the terms.
