I have had this company call my family business for the past 2 weeks. THANK GOD FOR THIS WEBSITE AND ALL OF THE INFORMATION PEOPLE HAVE PROVIDED HERE ABOUT PROGRESSIVE BUSINESS. I am writing this because they have been calling from a blocked number and asking who is a HR person and if they can speak to them I ask them who they are they give me a name and then I have to pry about where they work. I have called their 1(800) number and told them to take me off the list. They told me that they took me off but I have to tell each caller to take me off the list. I thought I did that in the first place calling their customer service. Well they don't stop calling! So I called the Pennsylvania Attorney General's office and they told me that after I contact them and asked to be removed from their calling list to then file a complaint with my Attorney General first (I forgot to mention I am from Oklahoma), and my Attorney General's office would be in contact with them. Start taking notes everytime they call and file a complaint in the end, though it might take awhile, it will be taken care of. Here is a link to a document from the Federal Communications Commissions about how crummy they really are! http://www.fcc.gov/eb/Orders/2008/FCC-08-145A1.html

Both of these should help you get them off your back.
