They do not refund money!!!! I purchased a 16tb external hard drive, when it arrived it was only 8mb hard drive. I did a dispute and they said I would receive a refund in 5 - 20 business day.. it has been well beyond this time. I have tried to contact AliExpress many ways but none exist. Just a robot that repeats responses. I still have not received my refund and I refuse to buy another thing from a thieving company.
