Dell / defective computer

I have a defective computer with a 3 year warranty that is good until August 2008. I have been on the telephone with their consumer resolutions for 2 months. After numerous test on the computer with their technicians in Phillipeans and India nothing has bee done. Around 2 weeks ago I was speaking with Hamamma in India and she was sending a local technician to my home to replace the viedo card and hard drive, after she decided that we were not getting my computer fixed long distance. I was leaving on vacation so she said call when I returned because I had to be there for them to come withing 3 days or the order would be cancelled. I called her twice and e-mailed also with no return call or E-mail and was finally contacted by some one named Siddharth Rep ID [protected] who e-mailed and did call Feb. 8 at 2:25pm. I did not know he was to call then so I was not at home. He said he would call again today and I have waited all day for his call. I probably live within 20 miles of a new Dell plant and this is the service I get. What good is a 3 year warranty if you can't find some one to honor it. I do not know what else to do. Do you have any suggestion? Any help will be appreciated. Also everything has to be done on their schedule and I have other things to do besides waiting by the telephone for a call that never comes.
