These scum bags will never stop calling. The "Do Not Call List" do not work. These callers are on "The We Don't Care " list. I never ever answer a call from numbers I do not know. Blocked AGAIN!
Kept getting calls from 650-489-10XX...same people each time and each time I blocked the call with android, they would just call from a different extension. Got Blacklist Plus Call Blocker for free off Google Playstore and it worked like a charm, allowing you to block a range of numbers. Now anything coming in from 650-489-10XX is blocked...cool!
