Yeah I figured I should just ignore the delivery courier as I've already been lied to by the company saying they haven't received a response. I'll just let them refund me on their own (they're trying to claim insurance)

I realise there is a lot of miscommunication among companies and carriers so you could easily say that you claimed another box for missing and not the one arrived yesterday (as example)

Why should he even bother doing that?

When a driver comes up to your door their mission is to get your signature to confirm that you received that package.
Either you sign at "Non-Receipt" or simply ignore them since any of those will lead to a failed investigation, where you have to get refunded.

If they come to ask you what happened you can just speak bullshit as i suggested. If they ask you to sign of course say no
