My advice is complain bitterly to who is paying the advertiser and tell the advertiser you are doing just that.

godaddy.com are paying Tapjoy good money to advertise their service. Complaints straight to godaddy about this advertising is the last thing they will want, and Tapjoy will not want godaddy receiving complaints about their service.

Kick off at godaddy and tell Tapjoy you are doing just that. I reckon they will pay up. If you complain just to the advertiser there's a good chance they will ignore you.
