Amazon driver walked through my front door, Amazon says don't call the cops

this literally just happened to me. my 3yr old autistic daughter is in my Livingroom with her therapist and an Amazon driver walked through my front door without permission and saw the ABA therapists and claimed the instructions said to leave the package in the house (it doesn't)

I called Amazon customer service and they asked me not to call the police, I am going to call the police anyways, I am a single mother of two daughters. what was that guy doing, why did he open my front door and what was his intentions? was he planning to steal or attack someone?

I get packages from Amazon all the times, nearly every day and now I am afraid for our safety! I have to make sure to lock the front door at all times
