Am I overblowing things or do I have a case?

My son has been receiving ABA therapy and the therapist has been forging my signature with the intent of fraudulent receipt of payment for non-provided service. The issues with the recorded visitations with my son indicates that the therapist is charging for hours that she was not with my son. For instance, she said that she had visited for a duration of three hours while on the real sense it was only an hour and half. This person not only defrauded her employer by working elsewhere for wages but also exploited a child with a disability. I also suppose, that signing my name is also prohibited by the law. Isn't it? I don’t know; that’s why I’m here. I also think it could be insurance fraud. Since the time documented was not actually being used fully. I disclosed this information in the company. And she is suspended until further investigation is conducted. They say it will culminate into termination because added onto the evidence under camera footages that captured her coming to my house frequently, my testimony that I have never signed anything for her for nearly three months now.
