Windows 7 free upgrade issue - Dell not helping!

This is my first post.  I just bought a a new Dell Studio 435 XPS on 7/2/09 from Micro Center.  This system meets all of the requirements for the free upgrade(new PC, bought after 6/26/09, Win Vista Home premium)

But, when I went to register the system on the dell website, it said my system didn't meet the eligibility requirements. When I called support I was handed off mutiple times each person saying they would fix the issue.  While on hold I was disconnected after waiting for almost 45 minutes. 

I have a service request number, they even have my phone number but no one has called me back.  I'm frustrated and don't really want to stay on hold again, unless the problem gets fixed.

Any suggestions? 

Thanks,

Todd
