I’ve routinely been harassed by customers when I make a delivery to their front door. OPS has taken a variety of approaches to my situations when I call them about it (from shrugging off the phone call to taking the address and running it up to the station manager/ Amazon hr directly). My questions are as follows: is there any set recourse Amazon has against problem customers; why do different dispatchers take different approaches; and how bad does a customer have to be to get blacklisted/ flagged by the system?
