Unfortunately posting in this forum doesn't solve your case since there's no casino you mentioned above have an ANN thread in this forum, so we can't force the casino's representative to look into your case. But it does help every user in this forum especially a gambler to avoid gamble on this scam site. However have you post your problem on third party gambling mediator e.g. casinoguru or askgambler?
He already posted there as I've understand his statement below, too bad to OP to experience this but if that site is not legit, we cannot expect them to pay the money. These sites can't help as well as there are still no solution for this problem. If you have all the proof of transactions and you didn't violate any rules of that site, there's no reason for them not to pay you, not unless they have no intention at all. This is a reminder to gamble only with the good site with good reviews, winning the jackpot can be more stressful if you played it on a unpopular site.
