A MAN CALLED LOOKING FOR SOMEONE I DONT KNOW

Place keeps calling me even though my home number is regestered with the national do not call registry.  Furthermore I have asked this organization no less than 3 times to remove me from their call list.  I have resorted to filing complaints with the FCC and traking the date, time, and supervisor I speak with.  Who are these people?
