Unresolved Issue

How do I get someone from Dell to respond to my continuing issue.  Going through the various support pages sends you in a big circle.  I am really frustrated.

1. When I enter my service tag, it defaults to an Inspiron 1525.  What I own is an Inspiron 530s.

2. I have a continuing problem with the computer not recognizing the DVD drive.  When I click on "My Computer", there is no DVD drive shown.  I have had 7 sessions during the first year with tech support.  It gets fixed and then the drive disappears again.  Now when I try to contact Dell, the response I get is that the warranty period is up, even though this problem began immediately after purchasing the computer and frequently through the warranty period.  When trying to burn or copy a CD, I get error messages like, no DVD burner found or no ATAPI device found.  I have tried all of the self-help procedures including downloading a new driver.  Nothing works, and I don't know how to contact Dell.  I keep getting the website runaround.  Any suggestions, phone numbers or email addresses at Dell that might help with this.  This is extremely frustrating.
