1,700 bucks to paint? $2,500 for an apartment that they rented the next month? I'm smelling fraud, and I'm thinking they are committing a pattern of it, and that leads us to three magic words, "class action lawsuit." I would go nuclear on them, and start threatening a lawsuit that was much larger than the money they claim that you owe. All you have to do is recruit other plaintiffs to whom they did the same thing, which isn't that hard. Just the threat of you posting advertisements seeking plaintiffs should be enough to get them to back down. It makes them look very bad.
And furthermore, AJ aren't you black? If you can establish a pattern of the apartment complex singling out minorities this way, then that opens up a whole new can of Federal worms. Threaten to report them to HUD for discriminatory practices, and HUD can set them up in an undercover sting operation that generates six-figure fines. If they have half a brain, they will pay you off immediately to shut you up.
Or just pay the money. None of what I am suggesting is very nice. It's up to you. I think you're being fvcked with, and my attitude is to retaliate ten times harder.
