I wish someone can launch an investigation to identify if the seller is defrauding me or if AliExpress is also in on this. The seller messaged my account that the product (treadmill) was not available and if I would change to a lower cost one. Since I did not see the message, I did not reply. The next thing I knew I received an email from AliExpress stating that my order was delivered and gave me a Fed Ex tracking number including routes/time stamps. I searched on Fed Ex using the tracking number and found a different product (office chair) delivered to a different location (not my front door). I called and the Fed Ex rep told me that particular tracking number did not match my name and address and that the shipper gave me the wrong tracking number. I reported this to AliExpress and AliExpress said that since my order status was "partially shipped," I could not file a dispute!!! I contacted the seller and the seller said there was a shortage and to wait instead of rendering my refund request. Both the seller and AliExpress ignored their email notification that stated the delivery had been completed and a phony route history was created using an erroneous tracking number. I have reported this to my credit card company. I really wish there is some kind of international law enforcement to deter thieves like them.
