If the company that you paid money to for services has filed for bankruptcy protection, you cannot bring a lawsuit against it in that there is an automatic stay in place from any such lawsuit under bankruptcy law.If the contract was a written contract and the person who signed the agreement for the bankrupt company did not sign on its behalf, but rather individually, you might have a basis for suing that person individually for the money paid where no services were rendered. As such, you should carefully read all written documents you received concerning the transaction you are writing about.If there is a criminal investigation pending concerning this business and its representatives, you should contact the police department who is doing the investigation about it in order to make another report about what happened to you. You cannot file a criminal case. Only the district attorney's office can.
