Unacceptable to charge me full price.

I made an appointment with a doctor at Intercare Fourways for 2 June 2015 at 7am. The morning I arrived I was waiting outside because all electricity was out. Eventually someone came outside and told us to go in, and that it was dark because the power was out. They established that it was not loadshedding, and that the backup generator is not working. I had to wait in nearly pitch dark for longer than an hour. After that I was told to come back the next day, I told them that I can't take another day off work, and they shufffed me in the first available doctors room. The appointment also took place in the dark. After I was done, I had to walk around and ask the staff what to do next (I could have just walked out and no one would have known). I filled in my name on a piece of paper and I walked out. You dont have a copy of my ID or my medical aid card. I am asking for a reduced rate because of the inconvenience I was caused. I had to sit in the dark and didn't see the doctor I booked for. I am willing to pay, but a reduced rate. There is NO WAY I am paying for what I experienced that morning. It is unprofessional and UNACCEPTABLE.
