Therapist didn’t show up and now they are charging me

I recently thought I give therapy another try through insurance this time. I saw the therapist for intake and she royally messed up the schedule. Anyway long story short, she didn’t show up to two sessions after I waited over fifteen minutes and now the company is trying to charge me no show fees. They are being extremely difficult about it, even though they should have all the evidence since it is an online system. Is there any state oversight (California) that I can report them to?
