AliExpress customer service is a joke!! I have purchased an item from NAVIFANS Multimedia GPS Store. I have purchased a head unit for $420 (clearly states you can return it in 90days which is still on their page). It is a Plug and Play item. So all you need to do unplug the old cables and replace with the new ones. We have installed and didn’t work. We have contacted the seller as item doesn’t work. He wanted us to do some tests and confirmed he will replace the faulty item after tests. We have done and confirmed that head unit doesn’t work. After confirming he wanted us to do more tests with videos. We have done them all. Now they want us to cut and connect the wires to make it work but I’m sure they are buying time. They wanted us to damage the items wiring. They sent us all the cutting wire photos etc. So they accepted it’s faulty. I wanted to return the item or a replacement but he never answer this a part from “friend corporate with us it will be very expensive” So I decided to contact the AliExpress customer service which is the BIGGEST JOKE. They have ignored first 2 attempts. I have kept on trying and figured out “THERE IS NO WARRANTY IN ALIEXPRESS!! For even any fault items. (They said depends on the seller but there is not a time period. So with my personal experience there is no Warranty at all) after another attempt customer service send me an email they can’t see any problem so they closed the request. I have tried. One more time they closed the ticked as we have to deal with seller directly (I have tried many times). Final one says we have to contact the seller as they sent him to send me a video how to fix video. I have purchased so many item from AliExpress but this experience ruined the image of AliExpress. I will pay a little more and buy everything from EBay and they deal these problems in no time and EBAY HAS BUYER PROTECTION AND EBAY MONEY BACK GUARANTEE. I can not even leave a bad review for the seller because they only allow to reviews in 30days of purchase. NEVER BUY AN EXPENSIVE ITEM FROM ALIEXPRESS or you will loose over $420 like me AliExpress order “8184603602448459“
