I am in San Jose, CA. and just had this number call my home number, too. I am also on the Do Not Call list. I don't answer numbers that I don't recognize.
They keep calling me at least twice a week FOR YEARS. I kept ignoring the calls by hanging up. Finally I got fed up and clicked to be connected. When I asked to be taken off the list, they hung up on me. I called back at 415-803-3279 and a recording told me to press 1 if I no longer wanted phone calls from them. They always start with "Hi! This is Dianne!" We'll see if they keep their promise.
