Here's a secret ..... These people want to sell you something. You personally, not a company. They don't make money wasting time talking to people they can't sell to. Your job is to convince them that they're wasting their time and to remove your number from their auto calling list.
The next time they call, and you recognize their phone number, answer in a pleasant voice and say "Good Morning .... Pizza Hut.... would you like to place an order" or "Good Afternoon .... Ford Motor Company .... how may I direct your call ?"
They'll immediately hang up and delete your number from their database.
