Please update us the moment you receive their response.

I've got a reply just now:

"Please remember that you are legally binding with your signature that you only received the package with one article."

He apologizes because it came to a misunderstanding on his side. He also said: "We will state in the requested investigation that you didn't got the package at all".

Then he asked me again to sign the PDF and hand it over to them (my signing is legally binding).
In the PDF I have to sign that "Me xx xx, did not got the package at all!".

and the last sentence: "In the course of this we will ask the driver why he left the package unattended under the carport."
