[Highland Park] Salesman

Hi neighbors, Wanted you to be aware of a salesman who is going door to door selling security systems. His identification read "Pinnacle" but he claims to be a contractor for GE. He wasn't rude, but he is very aggressive, and the only way I could get him to leave was unfortunately by closing the door. He may be legit, but I would hate to see someone get pushed into a contract. Thanks, Susan
