i'm 1 for 2 with bad FedEx experiences, but nowhere near your situation: snake delivery day, package not delayed (1030am) and en route, i took the morning off from work to wait and sign for my package since signature was required.
11am passes, and nothing. then my phone buzzes and i see the delivery notification. WHAT?! i read it over: "Delivered. No Signature Required." WHAT!!! i run to the door to look and there's her little box on my porch, set on the ground and it's 40°, no doorbell, no knocks, "LIVE HARMLESS REPTILE" clearly written on the box. unbelievable. thankfully she was a-OK.
i was just floored at the capability of FedEx to screw almost everything up besides delivering her on time.
i feel for you, but i'm sure he'll be okay. stay up their butts, tho! i'd make sure they knew my name and phone number by now.
