Complaint Review: The Computer Guyz

In June 2007, I brought my computer into The Computer Guyz to get a new hard drive installed.  The following day, I received a call stating that my motherboard was shot, and I needed a new one.  I authorized The Computer Guyz to install a new motherboard in addition to the new hard drive.
I continued to have CONSTANT problems.  November 12, 2009, I called another computer repair service to diagnose the trouble.  Lucky for me, I found an HONEST business, the technician showed me the hard drive installed in my computer; it was dated August 16, 2001.  I bought the computer brand new in 2002, so this is OBVIOUSLY the original hard drive.
Although the owner of Computer Guyz, Dean Taylor, has had PLENTY of time to rectify this FRAUD; to date, not a thing has been done to fix it.  I was offered a computer in exchange for my old one, but it had a 40 GH hard drive, (obsolete!), I paid for an 80 GH hard drive.  The computer Dean wanted to swap with me was a piece of junk, so I refused. 
I have heard nothing from him since; even though he PROMISED to make this right.
This is fraud, plain and simple.
