These people are a HUGE pain in the A** I have Charter cable and phone. I have blocked 12 different numbers and names on my charter phone service so I do not even hear the phone ring. Now I received 4 more calls with different phone numbers. Charter offers a free Call Blocker on their phone(in addition to the 20 number block) that this site will not allow you to post the name. It disconnects the call after one ring. None of these calls get through, but it is still annoying to have the phone ring at 8 or 9 am and wake you up.
