I understand Rollbit is reviewing your account related to sports bets. This seems pretty standard - many gambling sites will look closer at accounts with a lot of action on sports. No need to stress too much and if you've done nothing sketchy, it should get cleared up. Rollbit has a good reputation overall, so I'd expect them to be fair and reasonable here.
The review, investigation takes time and if it is an escalated process, it will take more time to handle it carefully without mistake. The user can wait for an official response from the team later and I believe when the team release their conclusion and answer to the user, it will be a final one.
They have good business and reputation so they will not want to make mistake to harm their reputation and business.
Just hang tight for now. The review may take some time, but if your conscience is clean it'll probably work out fine in the end. Try to be patient - getting worked up over it wont help move things along. Hopefully you'll get an update from them soon.
I agree with you. Waiting for the response, and in the mean time, let's stay calm. If the case is on the user, he will receive money when the review is finished. Creating many complains wont' help anything because the root is at the account and bets, not complains.
