YES! Block them all. The robocalls DO NOT stop. If you push the button to talk to somebody and ask them to stop calling you, they are rude and tell you they will call you tomorrow. REAL ASSHOLES! It's time for the government to step in and fix the problem.
AT&T is already working on that... I received a call the other day and it came up "AT&T Alert: Telemarketer".
Block those MF'rs!
Either this or let's go to war on the countries that house these scammers.
