The only strange bet that is going on, is the one that he placed with odds from 8.44
Usually, you do not place bets like this.
The only strange thing here is random shills making nonsense statements like this. Anyone care to comment on the OP's actual problem?
If there was something wrong with the 8x bet the site still had no right to manipulate other bets and/or confiscate customer's money including the deposit.
