I just got off the phone with Knowledge Net.  They claim they are not telemarketers.  I asked how they got my number and they said it was generated by a computer for them to do a survey.  They have called everyday for 10 days minimum.  I told them they are telemarketing.  They wanted to know if I used a telephone directory.  I told them "NO". I told them, "now I have answered your survey and you can take my number off your list.  I am an "UNPUBLISHED PHONE NUMBER".  The caller tried to argue with me that he had permission to call.  These people are BAD.
