Imagine you are talking to somebody in telephone. And while you are speaking, he ended the call. Actually, if he does this deliberately, it means an insult in most of the cultures. My question, this moment of ending the call while you are speaking, what is called in English? Imagine you need to tell what happened to other friends to show how this guy is rude, how would you explain it?
He hung up on you.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
