Got a call today at 11:32 a.m. and they left a recorded message saying that they were making a special offer to homeowners. A free home security system for placing a sign at my home...right....I'm giving them the benefit of the doubt and listing them as a telemarketer, though I suspect a phishing aspect.

That worked for me as well.  I didn't have to key in my #.  Took only 3 times.

I received a call from this number, no message left so I called it back.  I got a message telling me that if I wanted my number removed from their data base to press 1,  I pressed 1 and was asked to key in my number, I did as instructed and then received a message requesting I allow them seven days to remove my number from their data base.  I called back three more times and went through the same procedure, entering my number and on the forth call I received a message that my number had been removed from their data base.  It took about three minutes, no need to wait the seven days for them to do it.

Repeated calls from this number does any one know who it is
