Complaint about a casino or bookmaker?

1. Complain directly to the gambling business first, using its own complaints procedure. Include dates, times and amounts, attach your evidence and keep copies of everything you send.
2. The business has 8 weeks from receiving your complaint to resolve it and tell you the result and what happens next.
3. If you are unhappy with the outcome, after 8 weeks you can take the complaint to an Alternative Dispute Resolution (ADR) provider: a free, independent service. The business should tell you which ADR provider to use and give you its contact details.
4. You cannot go to ADR without first going through the business's own complaints process. The Gambling Commission does not resolve individual complaints itself.

The operator has 8 weeks to give you its final response.

1. Try to resolve the dispute directly with the operator's support and management first: the MGA strongly recommends this before you complain to it.
2. If that fails, lodge a complaint with the MGA through its online form (in English or Maltese), giving the operator's name and website, your username, the game, the amount in dispute and the date and time of the incident.
3. The MGA may ask you to verify your identity. False or fabricated details lead to the complaint being rejected.

1. Complain directly to the gambling operator first: read the terms linked to your account, use the operator's complaints procedure, include dates, times, amounts and evidence, and keep copies.
2. The GSC will not investigate until you have been through the operator's whole complaints process.
3. If you are not based in the UK and the operator holds an Isle of Man licence, use the GSC's online complaint form. Include copies of all correspondence with the operator and the terms you say it broke. Complaints must be in English.
4. UK-based players should use the UK Gambling Commission route instead.

1. Raise the complaint with the operator you registered and played with first.
2. If you are not satisfied with its response, you can lodge a formal written complaint with the AGCC (Regulation 238). Complaints are not dealt with over the phone: use the AGCC's contact form, email or post.
3. An AGCC officer first tries to settle the dispute by agreement. If that fails, the complaint is investigated and a written preliminary determination is issued; if either side rejects it, the Commissioners hold a hearing.

1. Try to resolve the dispute directly with the gaming site first: check its terms and conditions, then follow its formal complaints process.
2. The site's formal decision can take up to 90 days. Contact the AGCO if you have waited up to 90 days without a resolution, or if you think a regulated site has broken the rules. Complaints about responsible gambling, possible illegal activity or advertising may not need the site first.
3. Use the AGCO's online iAGCO service (no account needed) and have the site name, your player ID and the site's complaint reference number ready. The AGCO says it cannot get your money back or make a site give it back.
