Dell Refuses to Provide Entire Purchase

I purchased a laptop from Dell. Included with this purchase was an Express Upgrade to the Vista operating system. From all the documents I was provided there were no time limits given to me. When I received my laptop with my packing slip there were no additional instructions or rebate cards for this upgrade. I figured the upgrade would be sent separate, sent to me via email or sent to me in My Downloads on their website. I have continuously checked for this upgrade now that the operating system is being more widely used and can be trusted. Not seeing any upgrade being given to me, I have contacted their support to find out where the upgrade I purchased with my system was. They told me that they will refuse to give it to me because they put some time of time limit on the upgrade, which they failed to send to me in writing. Dell says that they sent mail. There is no way they could have sent me any mail because the address they had on file was incorrect - They deleted my mailing address and billing addresses and only had the one time use only physical address I gave for UPS to be able to deliver the package. I have received no forwarding mail from Dell, nor have I received any emails. They refuse to provide proof they have tried to contact me by any method. When I spoke to them in January 2007 regarding my system and upgrade, no one mentioned anything to me by phone. This is the worst customer service. You don't blame your customers when you make a mistake. There are a lot of complaints on the attorney gernal sites and BBB sites about Dell. I haven't hesitated providing more.

I purchased a free upgrade to Vista and I either expect a refund for this amount, a credit toward the purchase of the upgraded software, or the upgrade itself.
