I have registered my phone numbers on the "Do Not Call List" however I am still receiving unsolicited phone calls. The subject of this message is a call I received from [protected] (Ameritech). After answering the call and telling them to not call back they continue to call ignoring my request. They also come up on my phone as "unknown name". I did a look-up of the phone number to get the name of owner.
Let me know if there is some other way to block this caller.
