I told him I was in front of my building.

That's fine.

It doesn't conclude that the driver successfully delivered It to where you were located at the front of your building.

But that's not evidence, is it?

No - for the above reason.

He couldn't have recorded the conversation without my knowledge, right?

Extremely unlikely.

Very few drivers keep record of conversations.

And even if he tells the investigation service what really happened

The driver's word holds no value to verify consignments.

Thank you very much for your answer. So if I tell the rep:
1. that I could not be home during the delivery appointment.
2. that the delivery man called me twice and both times I told him I couldn't be there and he didn't offer me a new appointment later or the next day.
Does this seem like to be the best approach for you or would you add something else?
