So there is no hope for me? They will just take all of my money including wins?
Unfortunately, you aren't going to get the winning amount as Rollbit team have already made the final decision by listening to the odds provider. Rollbit usually return the deposited funds of the users. Now you should send
them a request
them to get the refund of your deposit at least. Rollbit may refund your deposit as you have never made any withdrawal from there.
