Does AliExpress support "Item not as described" as the reason for complaining?
That's what I always use on eBay, and I never lose!
A couple of examples:
Item: Cell phone
Problem: Does not connect to WiFi or Bluetooth (hardware issue, is my belief)
Complaint: "Item not as described"
Reason: "Described as 100% functional, but the item I received does not connect to WiFi or Bluetooth"
Outcome: Full refund, item sent back at seller's expense
Item: Used bench DMM, sold "as is, for parts"
Problem: Missing major parts
Complaint: "Item not as described"
Reason: "Described as 'For parts', but the item I received had major parts missing which was not disclosed by seller"
Outcome: Full refund, item sent back at seller's expense
The beauty of "Item not as described" is that it puts the onus on the seller to demonstrate why you're wrong. If they are BS artists, they would rather just move on quietly!
