Over the past year I have purchased 9 computers with a total cost of $7,112.91 plus tax. Many of them going on my Dell Preferred financing account so the rewards should have been a higher percentage. As of this date I have yet to receive a single $ in rewards. I have all the invoices to prove the purchases. I have lots of email correspondence about said purchases. I have an online chat log from one of the purchases that shows that I complained at that time that I hadn't received the rewards for prior purchases and the person on the other end assured me that my situation would be resolved. What am I doing wrong? I called customer care yesterday and got the run around for about 1 hour of trying to understand someone who could barely speak English.
