I called them and questioned them about this - they didn't even come down my street, and yet claimed that they "attempted delivery". The customer service person was honest enough to say there was no code for the driver to say "too busy, can't meet my unrealistic targets".
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%.
