Well, honestly, there is no legal ground to hold BC.game accountable on such an issue, and BC.game doesn't have to discuss anything with you before their decision to slash the affiliate commissions, since they did not hire you directly as a their affiliate marketer, or their promoter, or even ambassador, you probably saw their pay rate for referrals, got interested and hopped in, and now theyve decided to change the affiliate commission, it's up to you to either adjust to the new rate and keep going or hop out and look for another casino with better pay rate again.

BC.game didn't know the decision or agreement you made with your referrals, it is your business and not theirs, and if going by the new rate, you are no longer in profit after paying your referrals, like I said above, it's up to you to adjust with the new rate, or quit and look for another casino with better pay rate for their affiliate program.
