After the bets won, they were all cancelled by Rollbit and I did not receive my winnings. They did not pay me my $10k+ winnings.
The support said the odds were wrong and odds provider voided the bets.
If an odd provider finds something wrong with the odd provided or any other reasons like manipulation in the sports and such things, then they can void a bet or bets placed on that sport. It's hard to prove if that only happened with you.
Generally, the odds providers have business with many gambling sites. If you can bring some evidence from another gambling company that in the same event, in the same market that other gambling site did not void the bets especially the bets those were lost then you may have strong evidence.
