I forgot about my appt back in May, totally slipped my mind. I had to pay more than the copay for the missed appt because it keeps the counselor from booking another appt. Yes it seems unfair to pay for services not rendered but it is business. I can understand truly.
I personally would not say much to the counselor about it because this is standard practice in that world. You will find this in every practice, maybe he has bad timing but it is standard. My daughter was seeing a therapist and I decided to treat her as an adult and let her make her own appts since she was 18. She never told me when they were but missed two and we had to pay for both appts and yes the therapist was not very happy about not getting a call or an apology for the missed appt.
Also if he's been a good therapist all these years and this was the only instance of a communication breakdown maybe it's the time to overlook it or if you're unhappy with the therapy maybe it's time to shop around.
