I'm also in the video.
At least that could explain why the driver showed up to the address without dropping off the package. If finding the package takes a non-trivial amount of time, it would add up over the course of the day.
It's otherwise just wild to me that the driver did 99% of the delivery and just noped out of the last 1%.
You have nothing to lose, it’s not like they could threaten to stop delivering your packages.
Problem you'd probably have is getting the judgment, if they show up at the hearing. Their clickwrap agreements are one barrier. Also, you have no relationship with them -- you weren't the customer (and if you were see point 1).
Would be interesting to see what type of claim would work. Maybe conversion (ie theft) if they delivered it to the wrong address. But if they just hold it at the depot, I don't know what claim you could make. Would probably have to take it up with the seller.
Honestly, finding a sheriff to enforce a judgement against FedEx property sounds like the fun part.
