I have ordered 5 products recently and because there is a so called service of combined delivery all products became one package in a certain country. Therefore a new tracking number has been issued. When reached the final destination country where it supposed to be delivered, the package was sent back because address was incorrect. I opened dispute for all the items. For 2 of them I got a partial refund because AliExpress considered it was my fault for being returned. Even though I provided emails from post office and tracking information as AliExpress requested, for the other 3 items judgement was that they assumed packages were received so no refund was issued. So it doesn't matter that they became one package and the whole package was returned.
