I got a call from these people, telling me about security systems and how thieves are cutting cords outside the home to disable systems and asked me if I was interested in updating my security system...when I asked how they got my phone number, the lady said" I'm sorry,I didn't understand that response, are you interested in upgrading my system"?..I did "F" no, and asked again, how they got my number...she again sAid she didn't understand my response..I said I was calling the police, she then hung up...I still called the police
