What did I do wrong?

I reported a child molester to the authorities. I was very unhappy with the way they responed to me! The dispatcher was like, okay? what do you want us to do about it? I felt like saying "what the **** do you think I want you to do about it". Was I wrong in calling the police? should I have called child protection instead? Or what should I have done? I hate people who abuse children. As I was once a victim myself. These people do not deserve to be walking the streets! They need to be put away! I cried. Because of the pain I know this young girl is suffering!
