I just reported this number as well as 460-321-0000, 460-324-0000, 469-322-0000 and 352-235-0000 to the FCC.  I recommend everyone does the same.  Fill out this form.  It only takes a few minutes.  These harassing phone calls have to stop.  Register for the do not call registry and report further harassment here: https://consumercomplaints.fcc.gov/hc/en-us/requests/new?ticket_form_id=39744
