Bonusgeek, I had the same issue like you a few years ago. I don’t want to reveal which casino it was, it wasn’t of Grand Prive. I opened an account at a microgaming casino. I deposited $100 and got $100 bonus. I risked my deposit, finally I reached a balance of $2783 after I finished wager requirement. All of my play action met their terms and conditions. But I wasn’t paid. I got an email form the casino, “It causes our attention that …….” they meaned I was a bonus abuser at other casinos. They said they shared industry information who deposited and played only with bonus. This would raised the risk of casino side if a player only deposited and played during promotion period. so-called bonus abuser was not welcome by online casino, because casino could not make money on this kind of players. Therefore, casino reserved the right to close their account. All winning due to the bonus would forfeit. Only original deposit was refunded.
So, Bonusgeek, this is the rule of online casino industry, in the event of any dispute regarding a wager or winnings, the decision of ONLINE CASINO will be final and binding in all matters” Probably it is unfair. Nevertheless, it is a case you accept or just leave. You can choose not to play with them if you can not accept their terms and conditions. If you chosse to play, it means you accept their tough sometimes damned terms and conditions. It is very simple.
That was one of the reasons I stopped playing at online casino and turned to casino affiliate promotion. Hope this helps you. Thanks.
