The drivers are not always malicious either. Sometimes it's bad training and/or user experience on their equipment.

I had several packages delivered which were "signed" for by someone named "through the letterbox". Similarly, one package said dropped off at the door/porch but no sign of it so I asked for a refund as I assumed it's been stolen... 2 days later my neighbour gives it to me because it was actually delivered to them, but the delivery person couldn't select the proper option to let me know so I had no idea.

My delivery status with Amazon is frequently something along the lines of "left in the mail room". I live in a free standing single family home in a neighborhood where every one has their own mail boxes.
