They called 1/16 @ 7:48p CT, and I did not recognize the number on my caller ID. They left no message on the ans machine. However, I called the number back. It is survey for politics, the message says "sorry we missed you and if you want to remove your number from our call list, please leave your number after the beep" that's what I did, no big deal. Hopefully, that will take care of them thinking I'm not home, and continually trying to call to reach me again.
Hope it works for you too!
Reported this number a couple of weeks ago and the number stop. Well tonight 2-4-14 started back up. I did not answer and they hung up without leaving a message.
