I think you need to send clickbank 30 emails to get a reply. I have heard that one affiliate had sent 30 emails to ask clickbank to reactivate his account and pay him. He sent 15 emails and a reply said they were investigating, another 15 emails and then he got paid. It cost him 6 months and during this time, he can't sell anything. The clickbank will not keep your thing in mind, they only pay attention to their own benefits.
