All I know that you can do is call the Better Buisness Beurua in your city and make a formal complaint. If you know these other people that they have taken money from get them to file a complaint as well. If it is money they have taken or services not provided you may also want to go to the police and file a report too. The Better Buisness Buerua(I don't know how to spell it) are the people that can take there license from them
