Tapjoy Failed to issue a credit to my account for Contract Killers. Cited the third party company said no, and there was no recourse Internet

I tried a free offer to sign up for freecreditreport.com, completing this offer would give me 471 glu credits. I did so around Aug 10. I just recieved info Sep 4, saying the the owners of the offer said i didn't qualify, no reason, but i didn't qualify. It took several days for Tapjoy just to respond, then to said sorry there is no recourse, which isn;t fair as i followed all rules and provided evidence to back up my complaint. This company Tapjoy is a scam, oh and this is the second time this has happened. I guess i'm a fool.
