USPS delivered my Af15 3.0 (which was shipped "registered") to a completely different neighborhood in my area (I thought "Registered" was supposed to be infallible).
The USPS phone system would not allow me to speak with a human.
A boardie who works for the postal service provided me with a number in which a human would answer. Within minutes I was on the line with the manager of my local PO, and she told me she would personally drive to pick up the package and deliver it to me, which she did.
CGC was not at fault though, as they had addressed it correctly.
