<human>: I live in a small neighborhood with my parents.  About two weeks ago a guy dressed in casual clothes parked across the street in an unmarked gray Nissan (small neighborhood street) and came to the door.  My mother was a bit creeped out and we aren't even sure if it's legal to do door-to-door sales in my town so no one answered.  He then went and sat in his car for an hour and a half then came back to the front door and we did not answer again.  Then he left.  My neighbors said that no one ever came to their homes, just ours.

Fast forward a week he's back and my dad answers to say that we aren't interested, he gives us a business handout thing and leaves.  We told my neighbor (a cop) the situation but he said to text him if he was back. 

We called the number on the flyer but got to voicemail and left a message that we weren't interested and to not come back to our residence.  Then a few days after that the guy was back but my mother was home alone and never called anyone (e.g like the cops) about it.  He left another flyer on the door.

Can we report the business?  Call the township?

Can you give me the gist of the text in a nutshell?
<bot>: roofing company seems to be targeting our house and will not listen to requests to stop coming to home.  Also participating in door to door sales which I don't know if it is legal to do so here.
