Up Level Rewards/Reward Zone USA review: Completed approved credits and never received prize

Back around the last of August through September, I was participating in a program called Up Levels Rewards, which you had to play online games and get approved deals in order to get credits toward a chosen monetary prize. I was approved for up to 8 approved credits by the company, but never received my prize. The program I entered was for a $750 PayPal gift card. However, each time I tried to contact the company (Up Level Rewards) they kept telling me wait. I had waited over a month. I had left several messages and have sent in documents that I have proof. I worked very hard doing the very high levels needed and spent cash doing free trials to get my prize but never heard back after sending in proof to the company. All I want is my prize that I worked so hard for and they will never see again ever. I have been ignored long enough, all I want is for Up Level Rewards to please give me what I got approved for by the company. Thanks-Doris Hickman.
