I have been trying to use my earned credit. One week an counting just to make a purchase. I have my credentials and all my dell info. Buy they ask me by email more and more info. I have chat with them several times, last thing is that I have to send an screenshot of my logged account plus and textual words that I authorize my purchases. This looks like a bad joke, screen are very easy to fake, and how is possible that having me on the phone they can't verify my identity/ownership of my reward. No words to describe... just bad costumer service and and horrible shopping experience.
