The Do Not Call list is nothing but a big joke as all they do is put the number in the computer which does nothing to stop the calls it helps them find numbers to call.
It's not a big joke... i just mean that nobody can consciously call your number. This is a robo-call system for sure. They are using a computer to randomly punch numbers into a phone like you did when you were three and talked to Elma Waters is Pittsburgh while playing with your parents phone.
