You can create a scam accusation thread against them with proofs, including transaction.

Overall, this casino is very shady. They were the ones who were asking for KYC documentation when people were winning on their website and most of the times were just blocking their account without a legit reason but... As I said, there were asking for KYC for anything and now the title of their thread is - no KYC. It's very hilarious, they had a great chance to develop legit, successful business but you can't expect that from a team of scammers.
