Warranty Logistics Inc. Office Depot Refuses to honor warranty paid for Irving, Texas

When I went shopping for a new laptop I went to Office Depot in Reno, NV.  The salesman convinced me that they had the best warranty company and if I paid extra I could basically throw my computer out of a moving car and they would fix it.  Well I didn't do that, but I did have a need to get my computer fixed.  I called and was told the damage was covered, but I had to get it "bio-hazard" cleaned first.  They instructed me to call my local healt department.  I did this and was told they had no idea what I was talking about.  I called several other computer repair companies and was told it was a ploy for them to get out of fixing the computer.  I called back and got a supervisor who agreed there was no such service.  He sent me the box to ship my computer in to get repaired.  A week later I got my computer back, wrapped in plastic with a big orange "BIOHAZARD" sticker on it.  I called and was told again that it had to be cleaned.  I had my IT manager take the computer apart so we could "clean" it.  He wrote a statement assuring that it had been cleaned and could now be fixed. I shipped the computer back to them via UPS and it was received by them on 11/17/11.  The computer came back to me on 12/2/11 still not fixed.  I called again, and was told it needed to be biohazard cleaned.  They are playing games and I am done.  I am doing a chargeback on my creditcard for the payment of the warranty.  I advise everyone else to never give them a dime.  The frustration level is not worth it. I have also called two times prior asking for a supervisor and told that one would call me back.  Surprise surprise no one ever did.
