What to do with neighbours parcel?

[CallieCat19]

So I took in a parcel last week for our neighbour a few doors down. I waited a few days to see if they would come and collect it but they didn’t. So I assumed maybe the courier didn’t leave them a note saying where it was so have tried to drop it of to them. Weve been round and knocked four times since. I know they are in as the lights are on and their car is outside but no one has answered the door. One time My partner knocked he said they were stood right in the kitchen so he could see them but they still ignored him knocking the door.
I tried again a few days ago and when no answer left a note saying we had their parcel and to please come and collect it but still nothing,
I’m not sure what to do at this point, keep trying? Send it back? Leave it outside their house?

"I know they are in as the lights are on and their car is outside but no one has answered the door."

Sheet of paper, write "pick up your parcel from [your address] by 6pm today or I'm sending it back" in large letters. Sellotape it to the car windscreen.

Find a great big cardboard box and address it to them, emblazoned with "Sony - Lucky Prize Winner!", "Grand First Prize" and similar, then get inside it yourself with their parcel and a potato sack full of glitter have your DH and one of his mates (ideally wearing yellow hi-viz jackets) place you in front of their door and ring the bell several times. They'll look out the window, see it and think "Ooh, that's not the Daniel O'Donnell CD we ordered!" and excitedly haul it inside. Then you burst out, murmur a bored-sounding in the style of Daniel O'D"Congratulations, I guess", chuck their parcel at them, empty the glitter everywhere by piercing the sack and swinging it around your head. Then quietly let yourself out.

It's the only language people like this understand.

Lol

Send for a door battering ram (£250 off ebay).
Put their front door in.
Roll parcel up their hallway.
Job done.

Love it

Just leave it on their doorstep, even if it is raining, and put a note through their door. Job done.

So... what happened to the parcel?!
