Sage Advisor yet again not paid on time

I have complained about this before. I am a advisor for Sage online and they "give" us rebates for clients brought to Sage. "give" is the important word because it takes them months for them to pay it out! I have sent 5 emails to them and nothing! Last time it was because my banking details were "invalid". This time, i have sent proof of banking details so i am waiting for the next excuse for them not to pay me. My advice - use another platform.
