Another week goes by and Rollbit is making millions and getting away with scamming their customers
The last information provided by Razer is that the decision came from Betby, their sportsbook provider, not by Rollbit themselves, and thus there's nothing they can do about it. The rule about sportsbook canceling bets is also already stated on their Terms and Conditions, of which you agreed upon signing up,
3.3. Sportsbook platform reserves the right to refuse, restrict, cancel or limit any bet.
I am sorry that I have to tell you this, but this case is as good as solved. Nonetheless, if you still want to pursue this matter, I can PM Razer on your behalf --since previously you told us that Razer set his PM to not accepting messages from newbies-- and ask him if Rollbit would want to take this matter to another party and see their ruling about this.
