Query: Faulty product, Extremely bad customer service.

I purchased a Rio S35S through the RioBlue website last spring.My first one lasted for 2 months before its "system" crashed and the customer service representative (after making me run though several month long hoops) finally said it was unfixable and replaceable. She had a new one shipped out to me after I sent in their faulty product at my own expense.Their customer service correspondance was largely ineffectual and very time-consuming. The entire process took me about half a year to complete, so you can imagine I was quite dismayed when the REPLACEMENT PLAYER I received ALSO CRASHED in the same manner, not two weeks after I received it.This was my worse internet shopping experience to date, and I warn you against dealing with this company and its products.
