Formal Complaint Digital Editions

How do you file a formal complaint about this product and the service provided through the help center/blog/call center/chat room?

My ebook causes the digital editions to crash

-Go to help blog

Blog info does not help Mac users/info does not help

-Told to contact help center

Chat takes 2 people and 2 hours

-They tell me to uninstall all adobe products and then reinstall digital editions

Does not work...still crashes

-Gives me a number for the call center

17 minute stated hold time (50 min actual) and 30 minute conversation

-Uninstall and reinstall is the only thing our script says to do. I can't help you further

Ask to see a manager to file formal complaint about help system

-Can't do that, go back to blogs

Help me!
