Update: Just spoke with an admin, nothing he can do about it. I guess it's time I say goodbye to this site. Taking my 43 referrals and millions wagered every week along with me.
Sad to hear that, I have nothing else to suggest since you've made your decision.
Just a small thought, with as many referrals as you claim it seems to really affect their earnings (to be honest 35% is a pretty big bonus). Let's see if there is a significant difference without your role going forward. There is a good chance that they will contact you sometime, but don't get your hopes up by it.
