I need your help...advice. I sold something on eBay and the winning bidder was from South Korea. I mailed the package the next day thru USPS Priority Mail. Three weeks later, buyer filed a charge back on Paypal for an item she claimed not received. According to the USPS online tracking , it was delivered 6 days later. I then sent the buyer (who has confirmed paypal address),and Paypal scanned copies of customs form with the tracking number and receipt from USPS which shows the details on shipping. However, Paypal is declining my appeal as they said I am not protected since they require a signature required delivery for items over $250. I am basically SOL. I am still in correspondence with the buyer and she said that she went to her post office and that they couldnt confirm whether the package has been delivered or not. She suspects that the item was delivered to someone else. Now, it will just be my luck if the buyer reverses the chargeback. If not, I will be without the bag and a negative balance ($805)in my account. I just dont know how to go from here. I thought presenting proof that the item has been delivered would be sufficient but Paypal would not reverse the charge back. Thanks for reading and any advice/tips would be greatly appreciated. Thanks.
