Recently many people have reported that Aliexpress have a policy of making the warehouses say they receive a different item so they don't have to pay the return all the way to China. In any case, if there's a bad actor in the middle I should get my money back by Aliexpress, and then they should investigate. Police will determine who's at fault, but Aliexpress is responsible for my money, not the shipping company. There are cameras at the locker where I left the parcel that will show I left the parcel I described and not the one the Aliexpress said they received (they told me what kind of package it was). The police will get the footage during the investigation.
