"Disappointing"

After about a year of waiting to get an appointment at the Orthodontic clinic, I finally got one but it was cancelled because the doctor wasn't in. I got another one but the time was changed for no explained reason. When i finally came for the Appointment i was given at the Orthodontic Clinic, I waited for about 45 minutes with about 5 different patients who also had an appointment at the Clinic. A lady finaly came and said we could not be attended to because of some problems with the Clinic. There were no further explanations, we just had to leave. I have a terrible underbite and it only gets worse as time goes.
