It could be considered malicious prosecution as well as potentially slander, fraud, and other causes of action. In addition, there could be some violation of the state Fair Debt Collection Practices Act but not the federal.
To pursue them you would have to hire a lawyer and file a lawsuit in the state court system asking for damages and, possibly, seeking an Injunction against them continuing with actions such as this. There is no state agency which would directly regulate their conduct so the courts would be your only recourse. You could possible collect damages, punitive damages, and attorney's fees if there is a violation of the state Fair Debt Collection Practices Act.
While, in theory, you could bring the lawsuit yourself without an attorney realistically this would be way too difficult as there are so many potential causes of action that it is going to require a great deal of legal knowledge as well as legal research to pursue the case.
You may be able to have the same attorney represent you in the matters before the board as well as the lawsuit.
