It's normal for them to be scammers. They still send me invitations to play, even though they stole my bonus winnings and even my deposit (which is unacceptable, and no self-respecting bookmaker would do this).
Sportbet.one is a shitty, moneyless bookmaker run by kids who live in their parents' basements.
These bastards accuse all players of arbitrage or bonus fraud in every situation. Just check their reviews online; everything is clear. It always concerns the same case, and their verdict, unsupported by evidence, etc., is always final. This seems to give them the right to steal players' balances.
They should have been jailed long ago, but since they're an offshore bookmaker with a worthless license, they can still steal deposits.
I'm not trying to defend this casino you're mentioning, but based on what I've read here, their author seems to be giving a good reply. Have you tried contacting their
support@sportbet.one, which was provided by someone, I don't know if it was a staff member of sportbet.one?
Maybe you should first contact their support team to resolve your issue or their issue with you, dude. Especially if what you're saying is true, you can also provide proof.
Then, you wait for their response.
