ohhh am I mad...

I had an issue this morning where Vista would not work at all. Nothing would load and it kept hanging. So I try and use dells online tech support chat. I enter in my service tag number and it says I do not have a warranty, however, my invoice(both of them, the one that came on the box and the one they mailed me) both say 1 year limited , 24x7 technical support, mail in service and some other stuff.

I've been either on hold or call dropped by dell's bangledash call center
