Let me tell you how Ali Express conned me out of £600. I bought two types of headphones from two different sellers. In both cases aliexpress assured me that I could possibly return the goods via InPost Parcel Machines and receive the money paid upon return. One headphone was faulty the other was a quality failure, so I decided to return them. I reported everything in good time to Aliexpress, after which I was informed that I should receive an SMS with a code to return them via InPost parcel machine. Of course, I did not receive any codes via SMS and my contact with customer service resulted in replies of "be patient" and "no problem". In the meantime, the deadline for the return of the goods and also the refund of the amount paid had passed. The subject of the return closed automatically in the system. I monitored and emailed Aliexpress several times and finally the parcel codes were sent to me via email. I returned both parcels immediately using the code at the InPost parcel machine. As you can easily guess I did not receive any refund of the money paid despite the return of the goods. I emailed repeatedly and also spoke to the person on the customer service chat. Of course, they accepted the request, but the next day I received the information that they do not have any proof that I sent anything via parcel machine. We all know very well that InPost Parcel Machines do not print any confirmation and do not even send confirmation of the return parcel by email. (I have returned goods from other shops in this way many times and never had a problem, and never received any confirmation from InPost) Summary: AliExpress sells goods with the possibility to return via InPost Parcel Post. Later, it makes it impossible to return the goods by not sending an SMS return code, drags out the issue so that the time for return expires and so the customer is left with no money and no goods. Do not buy anything there!!!!!
