Caller ID says unknown. Did not leave a message

No message

I received a call from this number and the caller told me that they would be in my area and I was chosen to receive an update to my security system for free. I asked her if the company had a website and she said that the name of the company was Safe Home Security. I looked it up on the computer and told her that she was a liar, then she changed it to Monitronics, then put a security specialist on the phone named Marko. He told me that the name of the company was Safe Home Technologyand gave me his number - 888-552-5712. I am filing a complaint with FTC.

I ignored this call because it seemed to be a telemarketer even though I am on a do not call list.  I see others have had the same experience.  Thank God I have caller ID.

"Hi. This is Nicole.  How are you today?"  I asked, "Who is this?", and she hung-up.  CID says FLORIDA.
