I filed a complaint online with the Better Business Bureau about Parallels HORRIBLE customer service and problems running the download. The next day Parallels emailed me to tell me that they were crediting back my credit card. We will see if it actually comes through.
I write this just to encourage you to contact the BBB online and file your formal complaint so that this lunacy from Parallels will stop. Shame on them for the wasted HOURS of my life (our lives) waiting on them to deliver services promised that never come to pass. Below is the BBB link. The form was very easy to fill out and the response was within 24 hours from Parallels. Amazing how quick they can actually respond when a formal complaint is filed with a big dog like the BBB.
