CPA is a problem with these situations.
Of course casinos will not pay when they are losing money. They are supposed to make money.
If they decided that the players were fraudulent…
I really don’t have enough info to make any kind of judgement, and one would need to hear the casino’s side too. It’s good that you don’t want to compromise a casino.
If it is a program that has a forum here – CAP has made inquiries for members before.
