Ok, so I'm guessing that this move is a step down from what you usually do, right? Is there anyone higher up then your dad? I know that it kind of breaks the chain of command and your father would probably be pissed about this but you are trying to get answers from him and nothing is coming from it. This has happened to me in the past at work and I have gone straight to the district manager due to the fact that I'm S.O.L. if go to my direct manager.

Also ask for reasonable explanation for the actions. Records of maybe what would lead to such a dastrict move.
