They have called a couple times over the last two days - never leaving a voice mail.
I answered out of curiosity today and the caller hung up almost immediatly without saying a word.

Hi y'all, got a call, same as most, no VM message left.  Just wanted to post this as call came on 18MAR14 so it is a current post.  Take care!  Thank bHo and the health care fiasco for callers like this, deadline is 31MAR14.

Reporting these calls does nothing. FTC does not care. That why the "NO-CALL" list is meaningless.

It is very frustrating to get calls from   people who have time to waste. Why do they keep calling if they don't want anything? I do not answer calls from unfamiliar numbers but I don't want my phone ringing for no reason at all.

I got a call from this number this morning for the first time. I'm sure they will make several more attempts. Normally I answer and sound very angry. When they start their spill about whatever it is they are calling for I say "NOT INTERESTED" then hang up on them! Some times I feel sorry for the person on the other end because it's just someone who is trying to do their job, and more than likely they are dialing blindly from a list they were given when they clocked in at work, and are reading from a script.  If you question them they as to what prompted them to call your phone number they get uncomfortable.  I find that they find a way to politely get off the phone when you as them questions about who they really are, and how they came upon your number, and who gave them the go ahead to call...
