I do not work for FedEx. I work for the book bindery that is making your books and CDs. My responsibility is to make sure your books and CDs are made to your specifications and shipped when we say they will ship using the shipping method you choose to pay for.
Believe me, this is enough on my plate.
Once the FedEx shipper picks up the boxes and puts them on the truck and I send you the tracking numbers, it is not my responsiblity to make sure FedEx actually takes the boxes where to the address on the box by the time they say they will.
