Something seems wrong with my order. On the Apple order page, status changed to "Shipped" a few hours ago and says "Arrives Sept. 16". I never received an email notification that it shipped. When I track using the tracking number, it says "Label Created" and "The delivery date will be provided as soon as possible". When i try to track by reference number using either the serial number or order number, I get "We could not locate the shipment details for this tracking number". Any suggestions?
