Get 2 or 3 calls a week from 970-931-4758. Then when I answer, they hang up... A call back gets either a busy signal, or "I'm sorry that number can not be called as dialed...etc...."... I have come to believe the "Do Not Call List" is a joke. I report calls, and I report calls, and still I get them.... I'm older, and disabled, and often getting to the phone is difficult for me... HOW DO I STOP THIS??????
A much easier and more readily method to block calls is to set up a fake name in your address book on your phone. Enter the number and select "block caller". You can add quite a few numbers to each name. If you fill that entry, just add another name.
