EDIT: I have received an email moments ago saying as an exception they will pay my winnings + my deposit. I will mark this complain as SOLVED as soon as my withdrawal has been processed.
That's interesting! I'm wondering what are the exceptions here. The odds provider is Betby at Winna. Have you ever been limited by other sportsbooks with Betby provider? You should verify whether you are allowed to play normally or not after getting this withdrawal. Some other betting sites confiscate the deposit of the users after flagging users account for suspicious betting activity. But Winna has completely taken a reverse step here.
Yes, I've been limited before by bookies using betby as the odds provider. But the MO was always: getting limited and then being able to withdraw. I have been limited at winna.
