"Cancelled appointment"

I recently attended my appointment at the clinic. The doctor did not show up and nobody was informed they were not coming, the staff were not informed.

I had been waiting for this appointment for many months and had at least 2 rescheduled appointments, I was supposed to get a lung function test many months ago but I had to keep phoning and asking for this test to be done before I saw the doctor as I knew there had been a big change in my lung function and I would do anything to stay out of hospital as I have experienced 2 long stays previously. 

There was at least 3 staff on duty and they did not know what was happening, a complete waste of money and time, surely the doctor's secretary should have informed them? I had to refuse a lovely invitation as seeing my lung specialist was more important!
