OfficeMax Bogus Computer repair Federal Way, Washington

My computer cannot open the file from the shot cut on the
desktop screen. I ran the antivirus program and found no virus, so I bring my
computer to OfficeMax since I have the free system screen coupon. Drew the tech
guy over there was nice and told me that he need to get the system diagnostic
and fix for $129.99. And he said if it not fixed, I will get a refund so there
are no risk for me.  So I pay...I left the computer with him overnight.  He called me the next day and said that my computer was fixed. So I pick it up and bring back home.

 Now it worst, not only it wasnt fixed but my other programs were wipe
out (my calculator on my window, my photoshop ect.) and my cd/dvd drive
is  not working  also (It work fine before I bought  my computer in).  So I try to down load the drive from the Dell support site. It cant be installed too.  Plus, when I ran the antivirus program, I
found 2 viruses in my computer. I got them deleted then I bring the computer
back to OfficeMax, they kept it again over night. I came back to them 2 days
after and they told me that it cant be fixed! So I asked for the refund per
promised. The tech guy told me that I have to come on Thursday 19th
to get the manager to approve the refund. I came back and the assistant manager
told me that NO WAY point blank.
