I purchased Parallels Desktop 6 in August. I did not know I would receive a free upgrade to Parallels 7. So when Parallels 7 was released earlier this month I purchased an upgrade. Shortly afterward I receive notice I would receive a free upgrade to Parallels 7. I would like to see if I could get a refund for the copy of Parallels 7 that I purchased. I searched all over this website and cannot find a customer service email or contact information. Can anyone provide contact information for Parallels where I could request a refund?
