"Sleep clinic reception staff"

I have sleep apnoea and been on the list for a appointment for a long time. I live over two hours away in today's congested traffic. I have had two appointments made for last year and this year at 9:30am. After failing to get their on time last year, and I did ring to cancel as I knew I wouldn't make it in time while stuck in the heavy traffic. I rang and asked to reschedule for a later appointment next time.

When I got my new appointment for this year, again it was for 9:30am. I rang and explained of the trouble getting their at that time, because of the heavy traffic. But they said the doctor can only have that type of appointment at that time. So on the next appointment the same thing happened and I had left at 7am each time. So I rang again to cancel and I felt the manner on the phone by the staff member I spoke to was very aggressively rude. I wish I had never rung I am still waiting for another appointment.
