About a month ago I sold my iPhone 4 on amazon and the Buyer is just now contacting me trying to get a refund saying that he received a iPhone 3g in a iPhone 4 box which is not the case. I respond to him by telling him sorry but the item is as described in the description and told him politely that i could not accept his return. So i closed the claim. Now he opened an A-Z claim on me so I called amazon to see what I could do to provide information and they told me to provide serial number and provide previous contract information since i previously had it under a contract with Verizon. Verizon could only tell me the electronic SN but connected me with apple and said that she couldn't give me the Serial number but could confirm that it was a iPhone 4 and that it was currently registered/activated in someone else's name. She told me to provide the seller and amazon with her name and her number. So in my form to represent myself i gave them 3 pictures that I took before I sold the phone, Electronic Serial number that verizon gave me, and the apple rep contact number & extension. Do i have a good chance at winning this? I do not want to give someone their money back when i clearly sent them the right item and not only that amazon says that if i lose they get their money but i don't get the phone back.seems a little unfair.
