I checked the T&Cs again and saw there was another set at the bottom saying that they would take the bonus back when I withdrew AND that blackjack didn't count towards wagering requirements - I couldn't even withdraw my initial deposit less losses
1.Are you alleging that the T&C were changed
AFTER you made the deposit and started playing?
2. Or are you saying that you unfortunately missed the bottom set the first time you looked through them?
If the answer to #1 is yes, then I'd say you have a legitimate complaint and argument to get your full deposit back.
If the answer to #2 is yes, however, I'd count yourself lucky that they agreed to give you
ANYTHING back at all. If the T&C said that and you just failed to see it, I can't see how that's the casino's fault.
I do hope you get your money back, don't get me wrong. Your answer to those questions, I believe, determine who's responsible for the confusion.
