So the EXACT same thing happened last week to a fellow respected member who purchased a XS from me. The carrier signed it COVID and then last I heard delivered it to the wrong address. After doing some intensive investigating of my own the carrier is indeed liable for the loss. Procedure says... They can sign COVID only when the package is placed into the recipients hands. I would get on the hotline to the manager of the postal depot where it was delivered from and raise cane. I got my info from a long time postal worker friend and in our case the station manager admitted the post office was liable since the carrier did not follow proper procedure. Good luck man! That SUCKS and I think I will be not only highlighting the line SIGNATURE but also writing in PLACE DIRECTLY INTO CUSTOMERS HANDS! NO COVID SIGNATURE! for now on since insurance is useless with the values of X Metals.
