In general, I don't think there is anything to complain about. He knew from the beginning that Wolf.Bet does not support a leveling system. Why he is suddenly expecting rewards is not really clear to me!
That's not even the strangest part
Would you, or anyone else, for that matter, expect a gambler who (allegedly) wagered close to 300k USD at stake.com come here and complain about wolf.bet not giving him some bonus for wagering 1 million dollars as well as advising everyone to stay away from it when he probably didn't even wager a single dollar there? As I see it, that has nothing to do with rewards or their lack. Why not just keep on gambling at stake.com (or elsewhere) and enjoy whatever they are giving back?
