I was recently scammed by MoneyTree Casino after winning €1400 through value betting on a "0.03" odd drop. Despite playing fairly, they refused to pay out my winnings, claiming I broke their terms of service.
It’s pretty obvious that this is not the only value bet you have made. You made a €1400 profit from a ~€174 deposits. So, you must have made many value bets to earn that much. Why did you only share this bet?
I said it before, I don’t consider value betting or arbing cheating, but sportsbooks obviously don’t agree with this. In any case, they should at least let you withdraw your initial deposit before blocking your account.
