To be honest i dont know much about them, especially before registering to them which was a mistake, but who knew. I know for a fact though that when you google Rollbit scam and you find so many similar occasions with mine, something is fishy there.
Rollbit has been a very trusted platform and it's currently running their promotional campaigns on this forum and that's why I believe you won't get rugged by them because they aren't going to damage their reputation for $9379 as that's not a huge amount for them.
You'll see many wrong results on Google as most of the results can be manipulated ones. I believe you may soon get an answer from Rollbit's representative. I would suggest you to continue contacting them as share everything transparently with them, and I believe that they'll allow you to withdraw the money that you have on their platform.
You are right it is one of the few trusted casinos I know. I think there might be some problem. But if the support can be contacted with the correct information then it is possible to get a quick solution. If OP doesn't break the rules of course he can get his money back if he can prove it. Now I'll suggest op instead of getting mad at the OP. Errors are not unusual. If anything like that then of course returning the $9379 the OP claimed is no problem. Because this remarkable casino will never cheat their clients for a small amount of money. I think the OP should be more aware of his activities. Whether he has done anything outside the rules or not. I already saw in a screen shot that OP's support is linking his account to another account. Although I don't know the whole thing but if that is the case then OP must have acted break the rules.
