Contact your state attorney general’s office. We pay their salaries for these sort of things. Have all your papers, contract, dates / times you’ve contacted the liquidators, etc. in order. Sounds like this could be viewed as fraud and elder abuse.
I’m afraid small potatoes aren’t going to be paid much attention, even by conservative state attorneys. Even our local police department and district attorney are slackers.
Unless you make a LOT of noise and get a news special interest story going, your case is going to be filed in the “unsolvable” pile.
