I have only bet on the biggest leauges and games. Nothing shady, sadly ive won a few thousand.. They have provided no other information than that is has been escalated. If I had knew that they would do these kinds of things, I would never have deposited there in the first place. But now im quite concerned after reading all the threads about Rollbit in this forum.
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.
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.
