Two things I've ordered from Amazon were shipped by Ontrac. One ended up in front of our house on a little wall next to our driveway (not on the doorstep or even near the doorstep, which is up a flight of stairs. This wouldn't be a huge deal except it was raining ALL day on the day it was delivered, and there was no shelter where he placed the box, so the entire thing was soaked through. Fortunately everything inside the package happened to be wrapped in plastic, so my stuff survived, but who does that? It was one flight of stairs to my front door, which has a large awning over it and was nice and dry.
The second? Well, I spent a good 15 minutes hunting all around my house today, since Amazon's website claimed it was delivered to "FDOOR" yesterday. I finally found it, after I'd given up looking, when I went to get my mail. That's right, Ontrac jammed my package into my mailbox (and it was partially opened to boot!) despite the fact that a) they claimed to deliver it to my front door, a good 50 yards from my mailbox, and b) I'm pretty sure shippers other than USPS aren't permitted to use mailboxes to deliver.
So I've complained to Amazon and Ontrac. Amazon says that there is no way to request that my orders are shipped via UPS, so I'm now forced to consider canceling my Amazon Prime account rather than put up with this nonsense. Sheesh.
