Family, if someone were hanging up on me and ignoring my calls, I would take it as a sign they did not want to to talk to me and not waste my time or energy on worrying about how to tell them off. Spend your time on something positive that you enjoy.

I agree with l4l. If someone is hanging up on you and ignoring your calls, he doesn't want to talk to you. If he's being rude about it, that's his problem. I would ignore him and stop calling him. Go do something you like.
