AliExpress screws bona-fide customers. They protect dishonest sellers, promise to refund but Never send you the money. From then on their so-called support will not answer your e-mails
I see that I'm not the only one. There is not much we can do. Telling your friends ?? Yes, may be.
I'm trying another tactic. I'm telling sellers that I won't buy from them because  of the deceiving and untrusty behaviour of Aliexpress. And from now on I only buy from sellers I know I can trus from past experience - unfortunately that is not much
