My recommendation is to contact Homeland Security, State Labor department, and IRS. That will take care of fraudulent activity caused by someone named Koh. Paying Cash to employees, underpaying employees below minimum wage and being illegal are something those agencies will take it seriously and enforce.
Now, as far as you crying out for being victimized, there aren't that many people who will help or be sympathetic with you. You decided to choose the opportunity given by quack and you have to bear the consequences of making bad business decision. Good luck! Please get over this mess and hold yourself together. God Bless you.
