Hi,
The address I used to send a letter to is a PO box address. However, it's an important letter so I opted for the "signed for, 1 st class delivery" by Royal Mail. On the tracker, it's been over 2 weeks now and it doesn't say any further than the post office I sent from and a "we've got it" at the top.. no confirmation of it received nor signed. Is this the norm for PO box addresses? I've contacted royal mail so awaiting their response but thought I'd ask here too.
