I think he sounds kinda rude, and mean. I would say "screw him" and get another teacher. You SHOULD NOT pay someone to talk down to you, I mean, you are HIS boss , you are paying him. So I would not take it. Either talk to him about it and get things straight, or just tell him you want a refund because it is not oing to work out. That you need someone more understanding, and less frustrating as a teacher
