Seller lying about having shipped? FedEx IE taking take 3-7 days to update tracking information? Seller marked my order as "shipped" four days ago.  The shipment status in AliExpress says "Shipment information sent to FedEx" and "Tracking information is updated within 3-7 days".

However, when I track the package on FedEx's website, it shows the same status -- the package is not yet received.

Does FedEx IE actually take a few days to update?  If the seller is lying about having shipped the package, do I have any recourse?

UPDATE: 5 days later, Fedex has now updated the shipment as "package received".  Clearly the seller lied.  Should I expect a partial refund?
