This sounds awful. I have had so much trouble getting packages deceived by Amazon Logistics. Sometimes they are marked as delivered but not really delivered. UPS on the other hand does a great job with my packages. If Amazon has issues with a company they directly control(Amazon Logistics), it is going to be a nightmare with a bunch of small independent contractors. See also people’s issues with OnTrac.
I can't have them deliver to work anymore because their delivery window ends at 8pm.
Same here. Packet supposedly handed to resident. No, it wasn't! And the carriers have even left packages on the doorstep (London) on occasion.
Because Amazon has decided to leave a profitable business to others?
Or more likely, it's pushing its costs onto others. We call this a "predatory customer" where I come from.
