hmm... i actually have this experience before. I did post it in here few weeks ago. Basically what i did was go to the Computer manufacturer n make noise.... . But for my case i used credit card, so i was able to use reason that i pay to Acer n not to the vendor. I am able to pressure them to force the reseller cancel my transaction. Since you paid cash, i doubt HP will be able to do anthing. but u could try. for me 2k, i go ahead shout at hp man. no face give man.
