FedEx Ground was (or so I was told) a separate company initially, purchased by FedEx, and hence did not have the same quality standards. I sent a largish box to Atlanta once for pickup at the depot, following instructions from their 1-800 staff. The package disappeared for days until they finally tracked it down to some poor driver who had been trying to find "Hold At Depot Street" for 4 days. I was then informed they don't offer a hold-at-depot service.
It eventually got returned to me, to my billing address, not shipping address. As a final insult, I opened the door to my flat just in time to see the driver basically throw the box (now mangled beyond belief anyway, trailing styrofoam peanuts and cardboard bits) the last couple of feet onto my stairs. He looked at me and just said "What." then walked off.
Amazingly, the computer stuff inside was undamaged beyond a few bent bits of metal and some cracked plastic. What else to do but to hire a repair consultant (ie. me) to repair the damage (ie. bend the metal back with pliers) fabricate a stack of invoices for a fair repair cost (ie. 99% of the insured value) before reshipping with UPS.
To their credit they paid the claim without question.
