Following a 30-day waiting period advised by Rollbit support, I attempted to reactivate my account without success, I then decided to create a new account, experiencing both losses and, eventually, a notable win.
You was advised to wait for another 30 days to reactivate your account but the site didn't allow you anymore due to the self-exclusion, now you've created your account just to avoid this exclusion and that's a clearly violation of the terms. You should've asked Rollbit first if you can still open an account on their site before doing so, and not you're claiming the site stole your money where in fact they are just implementing their rules. Better to communicate this with the support and asked for a possible consideration.
