Recourse against unethical PM?

[Nancy Sathre-Vogel]

I have been dealing with a nightmare situation with a property manager. While I don't think she did anything illegal, there is no question that she has engaged in a lot of very unethical behavior. I plan to leave honest, straight forward reviews on Yelp and all other sites I can find, but I wonder what else I can do? I honestly think people need to be warned about this woman.
