I didn't read the whole thread, TL;DR, but as far as I understand, OP's betting was not accepted because he placed bets late or even after the end of the match. did I understand the essence of the whole problem correctly?
isn't that the casino's fault? if according to their rules it is not allowed, why is it possible at all?
The bets were accepted. The player wagered and won. But when he wanted to withdraw, they asked him for KYC, froze his account, and confiscated his balance. After that they started claiming he was late betting without showing a single case to back up those claims.
They made a ridiculous claim that the player made a wager at odds that shouldn't have been possible for a long time. It's interesting that when you take a look at a live match from their sportsbook, everything works great. The odds are adjusted in time, and if there is a technical problem, the markets get closed when needed, etc. I am watching a live match from Bulgaria right now. There is less than 3 mins left on the clock in the 4th quarter, and there are many open markets still that you can bet on. But when OP placed a bet with 8-9 mins left on the clock, that's considered
"late betting".
