It is security force. They called my house all week so I finally answered and the girl said we had entered a contest in a local mall and that my mother had won. When my mother gpt home they called again so she answered and they said she won free security system and the only fee is $60/month for a sheriff to come to our house each month. My mom said she wasn't interested but they have called three more times right after she hung up. They even tried calling under different number/caller I'd. I wouldn't answer if I were u!
