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 just stake.com to come here and complain about wolf.bet not giving them some bonus for wagering 1 million dollars as well as advising everyone to stay away from it when they probably didn't 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? Seriously, what's the point?
From what I understand, the percentage of returns for players who have reached the package I think is very small because they set a house limit of only 1% which is then multiplied by the amount of accumulated money spent. For 10,000 USD, the player will only get 10 USD
I didn't look into it myself, but I read somewhere around here that the rakeback amounts to a smaller house edge, and it is a significant reduction down to 0.7% at the very outside if I remember correctly
