As per the title, I upgraded to a new Iphone 5s last week so I decided (clearly foolishly) to list my old phone on eBay. It sold and I shipped it to the buyer. Then I get an email at half nine in the evening the next day stating that he has received the phone but it won't charge and it gained a chip (I took some pictures - not the best - before and have the serial number of the phone). The buyer said it was packed well and the packaging was unharmed so no idea how that could oh happened but that's unimportant to the fact the iPhone will apparently no longer charge / is dead. He has sent me pictures of an iphone 4/4s at charge battery screen - is this the dead battery screen on an iphone 4s ios 7? http://i.imgur.com/MBSfpBJ.jpg - that was his angle yesterday - now he says it remains on a black screen even when plugged in. Clearly I'm frustrated at a potential problem but what are my rights? It's clearly my word against his and in my experience that means ebay goes with the buyer but I'm worried he's tried to do something clever to the phone, messed it up and now wants to return something broken to me and get his money back. I had no problems with the phone at all so I don't understand how it could have possibly stopped working. I took pictures of the phone working, listed it and turned it off before the sale. Then three days later it no longer works at all and the 40% battery that was there when I sent the phone had gone. Seems a bit fishy to me.
