They called SEVEN times today in the space of less than ONE HOUR!! I have a Panasonic phone that blocks 30 or 40 numbers and I had programmed this company in a couple of days ago. My phone rings once or half a ring, stops ringing and then they hear a busy signal. They still show up on my caller ID. I filed a complaint with the donotcall.gov site. That seems to brings results most of the time. I urge everyone to do that.
