Abuse of authority by probation officer?

I am having problems working with my probation officer, who always turns everything I say around, accuses me of lying, and doesn't listen to any of my concerns. I took all of my classes and followed all of the rules I was given. When I voice a complaint about the probation office not properly informing me of some of the guidelines - I am told I am "difficult and argumentative" and now I have been given an excessive amount of extra classes and unjustified terms of my probation. I have never raised my voice or even appeared argumentative. Are there any cases I can reference about people being mistreated by the probation office? I have a review coming up soon and want to do some research before talking to the judge.
