Similar thing happened to me a couple of years ago with a 3D printer. Tracking showed it cross the country, get within 50 miles of my house, and then suddenly took off several states away. At that point tracking stopped updating. After waiting a while for Amazon to get past their "just wait to see if it shows up" threshold, they shipped me a another printer, which arrived without trouble. Two months later the original printer randomly showed up one day. I contacted support but they couldn't understand what I was talking about. After wasting a bunch of my time and their time, it seemed pointless. I didn't really need a second 3D printer but it seemed like it was going to cost both me and Amazon more time than it was worth to straighten out their mistake so I dropped the matter.
