This was the reason I stopped in blackjackfun. I wagered about 50 BTC - 60 BTC, but when I asked for the perks it was just words, really hurt me mentally, so I went to play another casino.
At what date you wager this amount and do mind telling us what perks you are asking? I'm not familiar with the VIP program of the casino but you should know the active perks and promotions before you wager that amount. The casino doesn't responsibility to grant your request especially if they are not offering it to other VIP players.
You accept what's the casino offering and don't ask more than that since they didn't force you to bet. Just leave just like what you did if you didn't like there current perks but posting publicly about your disappointment is a cool move.
