I've had the same experience. Every time they deliver via Amazon's service, I have a poor experience. They arrive in unmarked vehicles, so people don't let them in buildings. I can never get in contact with them when there are problems. One time someone ordered a gift to my place with amazon and I was notified that it was delivered; however, I hadn't received it. Amazon sent another for free 3 days later. If they are going to do a sort of Uber for deliveries they need to figure out some way to streamline it.
