Seller swears up and down that he sent the computer, but he is unable to provide me with a serial number, or anything proving he ever owned the said laptop. He says that once I signed for the package it was my responsiblity. He says it is not his fault. Can I dispute the charge with AMEX? I understand that the will ask for signed proof of delivery, well I did sign the USPS form, but didnt open the box until the next day, b/c I was in a hurry. Will AMEX side with me and take my word for it? I also have pictures, and a signed affidavit from my fiancee' stating that the computer was not in there. Will I receive a refund with AMEX? I called them up but they told me that they could not investigate the matter until I was billed for it, which is July 22nd. The funny thing is the seller had a high feedback. He also apparently used a friends store to process my card payment, as the seller and merchant charging my card were completely different. What are my rights? Please help. I have already filed fraud with USPS, and IFCCFBI.GOV. Help me please.
