I understand this and I have asked them to help me help them. They do not respond and only times they have is same copy paste message: you must tell us your other accounts. I dont have any and I tell them and ask for help and they only ignore. Ive never had issues on any others sites.
They are accusing you of having multiple accounts in their casino. Now when you join any casino they have all your information, there is a chance you will be caught doing something against their rules and that is what is happening to you. Rollbit rep replied to your accusation, they are still talking about multiple accounts. Now to solve this you need to prove that you don't have multiple accounts in that casino.
On the other hand, I hope Rollbit resolves this accusation as best way they can. Because Rollbit has quite a good reputation on this forum, they don't want to ruin their reputation.
