How do I stop these telemarketer calls trying to sell me security system?

Robocalls 2 to 4 times a day from many different states all trying to sell me a security system. Im on every do not call list imaginable Its a recording and they even ask if I want to be placed on their do not call and I select that option and still the calls come. For months and months now. Different number and area code each week. Im really ticked off. How do I stop it?
