Most casino disputes start with a stalled withdrawal or a closed account. The route to fixing them is nearly always the same: complain to the operator first, keep a paper trail, then escalate to an independent body. What changes by licence is the deadline and who you escalate to.

The UK Gambling Commission says issues relating to withdrawals continue to be the cause of most of the complaints it receives (Gambling Commission Annual Report and Accounts 2024-25, Gambling Commission). The Commission links this to identity checks and account restrictions that happen late in the customer journey, such as at withdrawal. Read our guide to identity checks at withdrawal before you deposit.

Before you complain

A clear case is easier to resolve. Gather these first:

Read the operator’s own complaints page too. It sets the contact address and the reply time you can hold the operator to.

Step 1: complain to the operator in writing

Use email or the form on the operator’s complaints page, not only live chat. State what happened, what you want (for example, “release my withdrawal of the amount shown on the date shown”) and attach your evidence. Keep a copy of everything you send.

The UK Gambling Commission tells players to give the business all the information, including dates, times and amounts, and to share any evidence they have (How to complain, Gambling Commission, read 2026-10-28).

Step 2: wait for the operator’s answer

How long the operator has depends on its licence:

Regulator Operator’s time to answer Time limit for you Source
UK Gambling Commission 8 weeks to resolve your complaint from when they receive it Not stated on the page we read How to complain, Gambling Commission (read 2026-10-28)
Curaçao Gaming Authority Four weeks for an ordinary complaint, extendable once by four more weeks with written notice Free complaints up to six months after the bet is settled or the incident happened Player Complaints Policy Guidelines, Version 1.1, Curaçao Gaming Authority (sections 4.2 and 3.1)
Malta Gaming Authority Set in each operator’s own complaints procedure (see the two examples below) Set in each operator’s terms (see below) Operator terms, read 2026-10-27

Two examples from the MGA-licensed operators we have reviewed, both from published terms and not from our own complaints:

Do not accept a vague “we are looking into it” as a final answer. Ask for the date by which you will get a decision, and write that date in your notes.

Step 3: escalate

UK-licensed casinos

The Gambling Commission says you must complain to the business first. If you are not satisfied after 8 weeks you can take the complaint to an Alternative Dispute Resolution (ADR) provider, which is a free, independent service (Taking your complaint to an ADR provider, Gambling Commission, read 2026-10-28). Points from the Commission’s pages:

Our guide to the UK Gambling Commission explains what the licence requires of the operator.

MGA-licensed casinos

The MGA runs a player-assistance function. It received 3,643 requests for assistance from players in 2025 and resolved 3,718, including cases carried over from 2024 (Malta Gaming Authority Annual Report 2025, Malta Gaming Authority). Of the complaints logged, 1,886 were referred to alternative dispute resolution in 2025, against 1,608 in 2024 (same report, Table 16).

The practical lesson from those numbers: a large share of MGA player complaints end up with an ADR body, so use the ADR route named in the operator’s terms. Our MGA guide covers what the regulator does and does not handle.

Curaçao-licensed casinos

Players of Curaçao-licensed casinos can complain free of charge up to six months after the bet is settled or the incident happened, and the operator must answer within four weeks (extendable once by four more) (Player Complaints Policy Guidelines, Version 1.1, Curaçao Gaming Authority). Keep the six-month window in mind: it is shorter than many players expect.

Read the Curaçao Gaming Authority guide to see how the register works and why a licence on the register may still have a status such as “assessment in progress”.

Casinos with no licence you can verify

If you cannot find the operator on any regulator’s register, none of the routes above is guaranteed to exist. A regulator may not handle the case, and an ADR scheme may not accept it. Document everything, tell your payment provider (see below) and avoid depositing again. Our guide to how to tell if a casino is blacklisted covers the warning lists.

What helps and what doesn’t

If the problem is your own gambling

If a complaint is really about losses you cannot afford, the right step is a break, not a dispute. See our self-exclusion guide and our responsible gaming page.

We have not made complaints ourselves and describe only what each regulator and operator publishes. Rules change; check the regulator’s page for the current process. Content 18+.
