I think I was a victim of ambulance chasers. What do I do next?

I was in a car accident and was contacted two days later by a group that claimed they were providing resources for crash victims. I was immediately funneled to a medical attorney, and because I was already disoriented by the entire process I was convinced to sign a contract with them. When I recieved communication from the insurance, it included a notice that this kind of thing is illegal for someone to do. I just want to know what I need to do next to protect myself, or how to find an ethical professional that can help me.
