I got calls from this number but never a message.

called about an hour ago, no message.

Missed call, RoboKiller app returned "Jim Shiers" as the caller ID.

did not answer and left no msg either.

I received a few calls from this number, but didn't answer because I didn't recognize the #.  There is a James Shier (or Shiers) that I found on the  internet and on Facebook that may be connected to this number.  Based on the things I read (nothing bad),, I can't imagine why he would be calling people he doesn't know.  He doesn't appear to be someone that would be doing marketing.  I'm going to block the number anyway because I don't know him.
