I understand that the USPS knows that essentially, the PO Box address is a virtual address and everything is to be delivered to CGC's offices.
However, I'm trying to figure out what Fedex did. Did they look up CGC's address and decided to deliver it to the physical address instead. Not sure if that's within their protocol.
I know for most PO Boxes, it's located at an USPS location so I'm unsure if Fedex could have delivered it to the "box".
Anyways, I agree that the poster complaining here isn't really going to help.
He should really just deal with customer service and in the worse case, give @PaulS.a shout out to see if he can of an assistance.
