On the caller id the name is DP. They call two or three times a week, ask for the owner. I am on the do not call list. When I told the person who called this time that I was on the do not call list and if they didn't stop calling, I would report them, she said "well, we were just trying to schedule an appointment to show you our free payment processing equipment, but if you're not interested we will remove you from the list. You don't need to have an attitude." And hung up.
Something really needs to be done. The do not call list certainly isn't working.
