Just wanted to note that the thread title has been changed from "roguish" to "Casino complaint". If a casino confiscates winnings and closes accounts of advantage players - that's roguish. But it they pay winnings and close your account, then that's their prerogative - it's not necessarily rogue.
If what the op says is correct and the account was closed prior to sending out winnings that is roguish imo. I also dislike the fact that they closed the account because they dont like the way he played bonuses. they have the choice to not not offer bonuses but the sudden closure of account is too drastic. hopefully, a rep from cwc can shed light on this.
