I truly hope your account has not been hacked, and it was an incredibly smart move to submit the complaint with us immediately. Speaking to the manager is also a good way to go, but on the other hand, I can imagine even a manager needs to investigate with the guys first.
What concerns me the most is that the gaming history has vanished. I find it hard to believe you can't see the cancelled, suppossed to be withdrawn amount fairly lost in the game. Did I get it correctly?
Moreover, where did the refund take place, please?
Normally, the history should be visible, so what happened with the account? Well, it must be a challenging situation. I expect the casino representative to explain this matter through the complaint.
Will surely be here waiting for another turn of events.
