Leaves no message, but has several number they use to get through.
Isn't listed.

I got harass through my phone while at work. I have been state to them that I am not interesting their offer and request them to delete my phone number and do not call again. They have many different number and keep calling me again and again. I think they bought my number from some where and try to get more my info.

Answering machine picked up on dead line. Obviously a robot call!

9:25am call on 10/25/15 from a male asking "Are you the homeowner?" I responded, "Who are you and how did you get this number?" He responded, "Lady, your name is all over the place, all over the country!" I responded by handing up.I will also file a written report to the Federal Trade Commission. They do a good job of cracking down on scam artists.

Sale call, don't answer
