This might be a bad scenario concerning filing a USPS Insurance claim too?
You don't have the damaged card to surrender for proof of the damage to file a claim. You might try asking your local Post office for some suggestions if the wrong addressee had to sign for the card . Appears this possibly might be a manipulated process by the buyer to get the card free? ( at least when I recently filed a missing card claim, I did have a damaged compromised empty box to surrender to my local Post office for some proof --which I hope will help my claim case?)
