Here’s what consumers have asked with answers from AliExpress staff and previous consumers.
If item does not arrive you need to prove to Aliexpress you did not get it. A letter from the carrier/Post Office is needed by them. I recommend contacting your Card provider not Aliexpress as in my experience you get nowhere with them.
Supposedly, but as soon you file a claim, you're on your own against the seller, and if the seller does not want to refund you (as it's always the case) for whatever reason, Aliexpress will not force them to refund you, nor they will themselves. It's a scam
The sizes run very small a large is like a size 6 and med is a size 4 and small is like a 1 or 2,
Aliexpress is a rip off outfit. They say buyer protection but there is none. If you don't believe that just try getting satisfaction or your money back. They are crooks and thieves
