I think you are too in a hast and you should take time to read the terms and condition and aooly it to your situation and any however you should be assured that support will attend to your case and if it is resolvable the support will reopen your account.
I just think that it is necessary to immediately explain to the player the reason for the blocking and the possibility of withdrawing funds, and not drag it out indefinitely
It's dishonorable and makes me nervous
Most of the time, Casino doesn't tell the gamblers what rules they failed to abide and the reason why the are being blocked or banned from the casino. I've seen few instances like this in scam accusation board. Though there are times where the casino itself is revealing the things you did when you make them do it like doing a scam accusation against them. You can try making a thread about your case in scam accusation and put some proofs that your scenario is real like posting some screenshots, email conversations, transaction ID or any thing that will prove your accusation a valid one. The accusation that you made had been done several times already and most of them aren't solved because most of them are just fake accusations just to make them lose customer. If you're serious about t he money that was locked to them, Doing a screenshot and providing some proofs is pretty easy.
