Why, on doing everything paypal said about returning a key ring to China, when a food mixer was ordered, did I get my dispute denied because tracking was invalid. The tracking number was issued by ELTA POST. I tracked it to China post to the address in Shanghai where it sat for a month. Also the same thing happened when I received 6 icing piping nozzles when I ordered a Food Dryer. I did everything I was supposed to do. Even printing the address Paypal gave me, in both English and Chinese. I think that the companies gave wrong addresses so that they do not have to refund, as they say they did not receive the returned items and their paypal account stays valid.
