Who called from 7206397968

caller id says alarm co. they leave no message.

Received this call about an hour ago. No message was left. CID read Denver, Co.

Called me and I picked up the phone. An automatic voice message told me that I "won"a "free" installation of anew alarm system or something. Hang up right away. It's a scam, don't bother.

Called and left no message.

Called, left no name.  When I called the # back, appears to be a telemarketer, you can press #5 to be put on their "do not call list".  I'll believe that when I see it!
