I can't get them to stop so I answer and place them on speaker phone and ask them to wait. They do and I get them to eat up thier minutes while I do other things. Lol costs them money to listen to me
Not a good idea to answer. Now they know your number is valid and they will continue to call you, using different numbers, just to annoy you. And, they will sell your name and phone number to other spammer lists.
