Cmon bro. You self-excluded yourself from one account knowing full well you had another account. Then you went through the trouble of signing into it, gambling there, and then ran into problems? Is that really such a shocker?

I have never dealt with Rollbit, nor do I ever intend to, but again, the best advice I can give you is to just walk away. Don't look back. Find something more worthy of your precious time while on Planet Earth.
