OP receive funds? or They are still pending / unpaid?
Just for understand, and turn this topic in a scam accusation one.
IIRC OP has received the withdrawal but not in a full amount of his winning, he only got 0.12btc instead of 2btc+. Owner of the casino claims that there is a max winning that can be cashed out from a no deposit bonus but OP claims that the rules of the max withdraw is added just after his 2btc+ withdrawal request.
