This shit happened to me with my RTX 3080 over the fall and it came very close to being returned to sender, and I would have lost my fucking mind if it happened. So in my case, I guess Fedex contracts deliver drivers sometimes who just do not give a fuck? On the second day of waiting for a redelivery, I was looking out of my house like a hawk. A Fedex truck pulls up, hangs out for like 2 minutes, a guy gets out in just plain-jane clothes (i.e. not a Fedex uniform) chatting on his cellphone, chucks two packages onto a neighboring porch, and then drives off. In that time he marked my package as undeliverable for the second time even though he never came within 50 feet of the door, let alone left a missed delivery slip.
At the end of the week, several phone calls to Fedex (completely fucking unhelpful) and requesting a fourth deliver attempt later, I get a phone call from the Fedex guy saying he was outside. Totally different guy this time. I chat with him and say thanks for calling, I was having a pain of a time trying to get the package actually delivered. He apologizes and says this is normally his route, but he was on vacation until that day so they must have sent someone to cover for him he clearly gave a fleck of a shit about anything.
Idk, glad I got it, but it's wild how completely at the whim of the person on the route you are to get your shit. I offered to drive to the depot 30 minutes away and get it myself when I called them on the phone, but they wouldn't let me. Idk what their phone CSR team is even there for because it seems like they're unable to do anything for people who call in besides just listen to them. I'd hate to have that job.
