I recently sold an item for around 900US and sent it off the next day, the day after that I got a letter from Paypal saying the transaction was unauthorised and the money was reversed from my account. I gave Paypal proof of shipping and they are looking into it. I emailed the buyer and they assured me that they did authorise the transaction, but I've heard it's possible for a genuine ebayer to steal someone else's paypal account or credit card and use that to pay for something. Is there any way of getting my item back? Even if Paypal finds in my favour, I don't want this scammer to profit with free goods using someone else's credit card details. Also can the ebayer file for item not received or place negative feedback if I try to expose them as a scammer and/or get police involved? Thanks for your advice.
