The telemarketer is wanting emails and phone numbers associated with the business so they can send free stuff.  When asked to stop calling they immediately call back and asked why you do not want free stuff.  Very rude and aggressive will talk over you and demand emails addresses and phone numbers.  They keep calling and the demands and attitude only escalate to a very uncomfortable level.  The phone number is in the eastern and southeast regions of Pennsylvania.  The BBB should be alerted to this "business" and its tactics.  Stay away from this number and report it if it calls your establishment.
