Could be a great app if it worked as promised

I have been using this app for about a week, the first few offers I completed were easy and earned me a good amount of money, but a couple days in, it became harder and harder to earn money because I am not rewarded for any of the offers I complete. I am constantly completing offers and getting no rewards. The worst part is I need a minimum of $10 to send the money I earned through PayPal, and I have been stuck at $7.24 for 2 days. If ever, and as soon as I get to $10, Im taking the money through PayPal and deleting the garbage app. By now I should have earned hundreds of dollars.
