this call comes in several times a week and sometimes more than once a day.  When I answer, it is like they know me right away, then they continue on with a sales pitch.  I tell them I am definitely not interested - but this is such a good deal you can't go wrong - I finally tell them do not call again and before he says anything else, I unplug the phone from the wall.  Putting calls on the Do Not Call List do not seem to make a difference, they just get another number.
