Is There a Governing Agency That Monitors Drug/alcohol Rehab. Policies and Practices?

I voluntarily entered a rehab in Long Beach for help with alcoholism. At the time, I was so physically sick with head-cold/flu, and when they put this lady in the room, I complained and asked to change rooms (I COULD NOT SLEEP) because she snored SOOO LOUD. I was literally thrown out in a hospital gown, I was so sick, they had been giving me all kinds of knockout drugs, I had no shoes, no money (they couldn’t find their key for the locker where my personal belongings were), was dangerously close to a relapse, but they threw me out on the street anyway. They actually locked me out when I was – or so I was led to believe – there for help with my alcoholism. This was in 2001. In 2006 they started billiing me for this so called stay! I want to report this to some State Authority that will take this type of therapy and put a stop to it. I was shocked they would even consider billing me for their “services” . Any ideas anyone?
