This one is STILL calling!  Didn't know number so I don't answer. Besides possibly getting put on a sales list of live answers, there is a New scam that involves them recording an affirmative "Yes" in your voice.  Any of these that come through as just City & State are junk. They are buying clumps of numbers or cloning numbers and blocking them doesn't seem to work. No message left. These scammers just keep calling from various new numbers. How aggravating!!
