The call block feature DOES work - my phone has blocked several of the numbers that I've entered. I'm not sure what the message is when they try to call, but if it's a robot, apparently it doesn't matter. They keep calling and my phone keeps blocking them :-)
They call several times a day. They always ask for my husband when they actually talk. I have asked them numerous times to please stop calling my home and they still call. How do I make them quit. They have even called after 9 pm.
