I'm wondering what you can possibly say to someone who has utterly failed at doing their job, while still remaining polite.
Background: my best friend, Janet, and I wanted to move into the upperclassmen apartments at our college. We needed to others to live in the apartment with us, so Janet invited Rita, a classmate, and I invited Paula, who was quickly becoming a new friend of mine. Rita ended up being okay, but Paula ended being horrible. She suspect that either she was jealous of my friendship with Janet, or that she sensed that Janet had bad self esteem problems and wouldn't fight back, so she started off making small comments to her when Rita and I weren't around to tear her down. It escalated, and Paula would outright bully Janet when they were alone. I found this out about all of this when Paula went too far and broke Janet's picture frame. In hindsight, what I had just learned explained a lot of Janet's odd behavior, and I felt terrible at not noticing that anything was wrong.
Rita and I told Paula we wanted her to leave the apartment as she had purposely created such a hostile situation. Unfortunately, she refused to leave, and as we could not actually make her leave, we contacted the Housing Department, and went for an appointment with the new assistant director.
The problem I have is with the way this woman handled this situation. I understand that she has to listen to everyone's side of the story, but even after seeing the evidence, including text messages and the broken picture frame, she still seemed convinced that this was just some silly dispute and that if we looked deep inside ourselves, the four of us would find that we really loved each other

She clearly believed Paula when she said that the frame must have fallen off the wall on its own, even though I pointed out the foot-shaped dent in it. I'm no crime scene investigator, but come on. She just said, "It could have gotten like that from falling, anything is possible." She finished the session with crappy advice about how we should all try to be more understanding of one another, and even tried to get Paula and Janet to hug! (she relented when it was clear they absolutely did not want to hug each other). Even if it had been just some silly fight where both parties were in the wrong, that is still completely inappropriate. I know she is supposed to be impartial, but she seemed determined to ignore everything and act as if this was just a silly, easily solved problem.
The Paula problem got better, as she moved out on her own, due to a combination of me refusing to hang out with her, as well as Rita, Janet, and I refusing to share any of our stuff with her. She got that I was serious about that when I took the TV remote from her and told her to get off my chair and sit on the couch that belonged to the apartment.
I am still bothered by how this was handled, and I want to send a complaint to the assistant director, as well as the head director. I'd like to basically say:
Dear Assistant Director,
I am very displeased about how you handled my situation. Either never do that again, or else find a job that doesn't involve helping others.
Sincerely,
Me

Only, not stupid
