I am a new user on this forum, but I supported this flag. I have read 90% of these posts on this case, and I think I fully understood what this is all about. Given that I have a lot of experience with sports betting, I can identify with the OP here.
First of all, FortuneJack accepted all bets. Why did they accept them if it contradicted their rules? The main question.
Another very important question - why were the bets canceled after the outcome of the matches was known? Why didn't they do it before? I'm pretty sure FortuneJack wouldn't void bets if they were losing bets.
Furthermore, it is very unprofessional to have rules, and allow in game to break rules with just one click. A lot of space is left for such cases. In my opinion, very tendentious rules and deliberately written precisely for such cases.
