I had £65000 in my account, won fairly. They educed the amount to £0 and closed the account. All emails to them are ignored. The telephone number on their contact page is for an online dating agency. Police won't help as they say it's a civil matter, take the to court, but without having details of directors etc there's not much I can do.
All we need is a phone number or address of the casino owner and we can pass it onto the authorities. I'd be prepared to give most of my winning to charity if only to bring these crooks/scammers to justice.
