1. USPS is the only carrier that has direct access into my building (because that's where the mailboxes are)
2. I was home all day and there was definitely no delivery attempt
I'm guessing they have SLAs in place with Amazon that penalizes them for late delivery, so they have to resort to such tactics.
We simply don't get mail at least one day a week, maybe two.
Packages are marked as undeliverable. But then they show up a few days later.
I've asked around and have heard that mailmen (mailpeople?) in my city just don't finish their routes everyday.
If that's because they're understaffed or too busy due to Amazon or just lazy is up for debate.
Amazon doesn't provide any discoverable way to complain about this either so I'm sure their internal metrics look great.
Eventually I googled the problem, and got linked to some random non-Amazon site, that told me to go find the generic "Help" link, and dig through a couple screens until I found a link to a chat interface (basically a "nothing here is helping me" link), where a robot would help me. The process worked perfectly and easily once I got there, but there's no way I would have gotten there on my own.
I suspect some people, when confronted with a missing item, will try part of what I did and just give up and eat the cost, especially if it's a cheap item. So the internal metrics look good, but that's not telling the whole story.
Black Friday, I got charged for the item but nothing else changed about my tracking. A few days later, after a similar search, I found the help link and got a refund. To this day, I have no idea whether my item ever made it out of the warehouse.
It doesn't seem like Amazon's delivery drivers know what they're doing at all.
I guess this isn't their motto anymore, because I've had similar experiences.
I'm sure it's some dark pattern thing so that their employees have to mark everything as something other than late, damaged, or lost since otherwise it eats into their profits.
The only time I can't use it is if my package is too big to fit, and that's rare.
That was December 11 2017. It never did arrive.
