Remain adamant with your dna. Do not back down. Your postie will always remember you as a liar otherwise.

As for your friend, if the postie ever questions him in the future he can just say the parcel he signed was for a completely different order.

I mean it's only the one delivery driver who handles my street/suburb.
He does seem like a good guy too, I'd hate to do him injustice.
I might say he thought it was an order he made with a different courier.
It's just if I remain adamant, wouldn't his supervisor keep pressing him about it?
