I bought several devices from a seller on ALi Express. The seller send me wrong device and I disputed the case. Ali Express took the seller side and when I appealed they did the same. Ali Express took the seller side again. If I presented my arguments to a naive person he/she could understand they point I was making and how i was spammed. But Ali Express did not listen to my points. It is obvious that Ali Express would take the seller side when they get their commission from the seller.
