This happened a few weeks ago: I bought an ebike and Fed ex ground dropped it at my door, he signed my name, and split. He didn't even knock. My wife heard him and called to me (I was in the next room) that she can hear it coming, so I went out thinking I had to sign for it, but he was gone quickly. The box on one corner was ripped up bad and someone either dropped the box and it landed on the corner or someone dropped something on the corner. The rear pannier was severely bent (the wheel wouldn't even move) and when I removed the pannier I realized the bolt holes were all ruined. Either way the force needed to bend the rear panier like it did had to be a lot of force. I imagine that was not best for a brand new electronic system and refused it. I am working on returning it now.
If at all humanly possible, when you hear the delivery person come- go out there, stop them, and do not let them leave without inspecting the box first. But if the box has been ripped up, you may want to refuse it and wait for a new one. Huge headache, after unpacking it, to decide you want to ship a bike back in a ripped box. All the support plastic strips are gone. The box is a 3d puzzle of stuff. Once I get it returned and get my money back I'll report on the whole story. Just don't need to poke the lion on here and have them read it.
If Companies are not going to require signatures because of COVID (I get it), delivery people shouldn't sign someone else's name. He didn't even spell it correctly.
