Contact your State's Attorney General

You need to contact your state Attorney General with this information and all the harrassing phone calls.  Get as much information on the company that you can and keep a record of the date and time of the phone calls or record the phone calls and give all of this information to the Attorney General and even the police.  You might also contact your phone company and tell them about the harrassing phone calls and see if they can do anything.  Good luck!
