I need to find a call blocker that actually works. I have Call Block and it is set up to pick up hang up and it keeps ringing and sending to voicemail. If I don't answer that party calls from a blocked number! I need something that actually prevents the call from going through (NO VM) and also blocks private numbers and doesn't limit the amount of numbers you block. This person is using multiple numbers. My home phone does this fast!! Please Help I am seriously considering changing my number.
