Hi OP, i'm sorry about what you're going through, but your account is still very new, how can we believe what you write when many RollBit users are still comfortable playing online, please include proof that RollBit is making things difficult for you and put it in a scam thread (not in this thread)
Yeah, we need proof. Its really that easy to make some accusations online but no showing of proof is really just simply trolling. 
Rollbit had been here for how many years, they did have a good reputation and recognition on crypto gambling space. Issues might raised up but its impossible
that they would be locking up some withdrawals without any reason. If they've been telling you to comply something or wait then there's nothing you can do
but to do such thing.
@OP, have you already contacted out with those above recommendations?
