Harrassment

I have asked a hundred times to take my number off their calling list and no results.  They constantly call and say we sent you information.  No infor ever sent and they don't even know your name.  Is there nothing we can do to get them to stop.  It is pure harrassment.  The government needs to step in and take this company out.  They get involved with other things.  Further more 0% of nothing can not be lowered.  Somebody do something about this company.
