Unprofessional

I booked my appointment 6 weeks in advance, on the day of my appointment, it gets moved from 11:30 to12pm, which I accepted even though it was a slight inconvenience. I get there to the staff not knowing that my appointment was moved (I had received a message 3hrs before my appointment), and then they require letters from my medical aid which I was never told of. Fine, I attempt to access them but there is no wifi/wifi password in the office, the Dr is also nonchalantly telling me about how she is booked for a 12:30 and has to leave. I did not move my appointment to 12, they did 3 hrs before my AP. I was not told from my phone conversations making the booking that they need medical aid authorisation letters and I’m being told the medical aid should have let me know when they should have let me know that they require that as I had told them 6 weeks prior which medical aid I was on. So Iv lost an hour, petrol, time driving to and fro for a service I did not get. A zero star would be the ideal rating.
