Looking at the screenshot provided, I don't think that you'll ever push this because you're at fault OP. There's the falsifying of documents that you've sent to them.
It's better to just accept the fate that has resulted in the termination of your account instead of trying to push it, which might cost you a lot of money. But, just like the others, I'm also confused with everything from OP and for the casino.
He needs to look outside of this situation, if the amount is really not worth to push thru that he may incur to spend his own resources along with the mental stress that it will bring to him, better move on and find another trustworthy casino to play with. Even if his principles is saying he needs to proceed what he is doing towards mbit. He should be practical these days. Just spread the warning signal to others. But he should not let this situation dictate his everyday life.
Yeah, if it's worth to breakthrough with it for the amount that he has there then he should pursue it. But if the casino is correct with the reasoning then he'll expect nothing from there.
However, with all of the words and stuff from different opinions, I'm still confused and OP has to clear a lot of things and I hope that he comes back for some clarity and the same goes for the said casino.
