I brought my computer into their service department a couple of years ago to replace a USB port that went bad. The technician fried my mother board. I went to the Office of Consumer Affairs in Fairfax VA and lodged a complaint.

It took a few months but I was able to get a new computer of comparable value. I'd suggest you all do the same. It's a very easy process to go through. They service complaints for any type of consumer purchase made in Fairfax County only.
