Very disappointing

This has been very disappointing experience, because there are no instructions on this app explaining how the rewards are earned, and that once Ive completed an offer for one category, I will not receive any rewards if I choose a different offer from the same category. Ive put my private information, that companies pay money to obtain on multiple web sites,but when I submit a ticket for a missing reward I dont even get a reply!
