They claim to be Impact Home Security.  They wanted to give me a free security system. I asked for a phone number to call them back and they said they couldn't give me one.  She said I can give you my cell phone number. She said if I lost her she had my number. I'm on the do not call registry.  The name came up as Regina Green on my caller ID. Pretty sure they are phishing.  Tried to get me to say yes... I said maybe. Said when I set up an appointment that then they could give me a phone number. I told them they were doing shady business no legitimate business is not going to give you their call back information. Free security system --- ha. Maybe so I don't know. Spam as far as I'm concerned and Shady as all get out. I was hung up on eventually.
