If it was really a bug, then it was handled rather properly.
The Player has already received Large Bug Bounty (0.2 BTC) plus his initial deposit back, and as a personal present from me, 30 Free Spins with minimum x2 wagering requirement. I am afraid this is all we can do here, I was personally curating this case and wanted to be 100% sure, that's why it took a little bit of time. The Player himself is a very gentle and polite human, and casino staff shared deep sympathy towards him, but in this case, there is nothing else we could do. We are deeply sorry for the inconvenience, but consider that our treatment, in this case, is entirely fair.
Actually, they didn't need to do any of this.
Why does this require me to sign in to gmail? Make it publicly accessible.
I''ve seen this countless times. Whenever you win big at these casinos they always say there was some type of bug or they wont let you withdraw for verification reasons. They are scammers plain and simple.
Just go away.
