Help i need your advice! I was Lied to during an interview what Should i do? I know it's illegal?

I went to an Interview with NCO financial and i was lied to during the interview; The interviewer said i was going to be doing collections and that i had a supervisor and i was the only person reporting to her. And that the other people sitting around me were collectors also but working with the city of Wilmington and they're all getting paid $9/hr. Turns out I'm working with taxes and it's not collections and the job im going to be doing is no where near $9--$13/hr job it's more like $32,000 per year job. He also said it was a last minute job they had to make up that's why i was the only one. What can i do to this scumbag? cuz i know he has the city under the impression that he's paying me what he's supposed to be paying me, but is paying me only $9/hr and putting the rest in his pocket. What can i do to this scumbag? Can i sue him? Because i know it's illegal to lie to candidates in the interview room.
