It's a more modern version of the mechanical "watchclocks" installed in buildings to ensure that guards make their appointed rounds. https://en.m.wikipedia.org/wiki/Guard_tour_patrol_system https://en.m.wikipedia.org/wiki/Watchclock
I have no idea how regularly USPS examines or audits their MSP data.
Source: I recently had a package stolen from the usps pipeline and was told this by their investigators.
Working for USPS is not a comfortable place to be. USPS kind of got taken over by Amazon traffic, and it's been an adjustment.
Definitely file a complain with amazon and provide the order number. They will lay down the hammer.
Lack of competition would raise the likelihood of eventual declines in service. Better for Amazon to put pressure on UPS to do a better job of running their business than to eliminate them all together.
why dont they send the first try with UPS, and the second with FedEx or someone else?
One time, I had a package coming via Amazon Logistics. It was marked as delivered but was not there. I asked for it to be sent via a different carrier but their customer service said they couldn't control that.
I guess nobody has built that feature yet. :(
Amazon says there is little they can do about it, except offer me a small credit on my account and file a complaint with their folks that handle the USPS relationship.
