I feel like bitching

okay soo...over a year ago I got in trouble. This November will be two years.
I went through the court system and got onto a 1 year probation. And recently I was told I could get off 3 months early because I did everything so quickly and what not. Basically getting off for good behavior ya know?
BUT that got fucked up because of other peoples incompetence which I am gonna explain.
Okay..so in the beginning I had to do a bunch of hearings to decide my punishment. My public defender said all should go well.
But during one of the hearings I hear the judge say something about me having a "substance abuse" problem.
woah woah wtf!? there were no drugs involved in what I did and I have never done drugs anyway.
I went through an extra physiological test to prove that I didn't have any sort of substance abuse problem. And the judge even agreed afterwards that there was no problem.
BUT they still made monthly pee tests a part of my probation and mandatory drug and alcohol classes. So wtf ever. I got over it.
Went on doing my classes. They spell my name wrong on the certificates they give me. f***in morons >.>
But to the part where I get screwed over.
I was suppose to do positive choices level 1 and 2. Which I now know means 6 months of classes. When we got to the classes we asked the lady if the program I was in was positive choices level 1 and 2. She said yes.
I finished the 3 months.
My probation officer told me that I was ALL finished and that I was an excellent candidate for early termination.
Sweet! wont even have to do a whole year!
For some reason I get traded off to a different PO and she tells me that I still have positive choice level 2 to finish.
Its a 3 month program. I was gonna get off 3 months early. So that means no matter what I have to do my full year of probation now because
1 - the stupid f***in lady at the classes told us false information (shes now fired)
and
2 - my first PO didnt do a good job and also gave me false information.
and of course they transfer me to another PO. Prolly cause they dont want me to get them in trouble.
So today I go to the classes all over again >.> Pay more money for something I dont need nor want.
I swear im about to go f**king postal and just started shooting people.
Why do these people have power over us when they are in no way shape or form better then us?
