So what do you actually want to know, whether we think you can/should report these people? Sure. Look on the State of California website. Whether you could get some money from a small claims court filing? Might not be worth the tim t would take you to put a case together and you would have to have documentation.
It’s obvious your first priority should be to replace them with reputable practitioners.
I think it is much more likely that they are just incompetent rather than practicing a scam. Sad but true. Ive seen so many.
After 40 years or more with my disorder and knowing many people in real life who have other disorders, I would never accept a diagnosis from a psychotherapy group without verification from a board certified psychiatrist. A psychotherapist told me 40 years ago that I had an anxiety disorder, period. Since then I diagnosed myself , with verification from professionals from that time forward and it turns out that I have one of the more complicated types of bipolar. Research these conditions yourself in addition to seeing the proper professionals. You know yourself best.
