AliExpress customer service is another name for supplier protection.The customer is treated to a long non progressive process aimed at breaking his justified claim.Tricks like order complete,no dispute opened,send a video preferably as long as "Gone withe wind",mock indignation that a supplier would treat a customer so badly ,we understand your frustration,we will not tolerate this behaviour from suppliers and the crowning glory "AliExpress is a legit site we take complaints seriously. The seller whom I purchased from refuses to contact,despite 7 emails from AE customer service.He remains on the site [Battery Sir Store],selling his substandard products to other unsuspecting souls thus AE are complicit and should stop claiming they are LEGIT.Advice is, dont buy through them its actually better to deal direct with the manufacturer.
