Carole, not trying to offend, but why did you wait for almost 2 years till they closed? If they didn't pay you in a month after it was sold you should of just talk to them and if no money take it to the court. Unless you can trace the owner of the business I'm not sure how to get your money back - I'd say talk to the lawyer.
