Unprofessional nurse

I called the Clicks Pharmacy Broadacres twice during the day to make an appointment for the clinic, on both occasions I was unsuccessful. I therefore rushed to the Clicks Clinic in Broadacres after work today and arrived at 17:53. The door for the clinic was closed and I heard someone speaking so I assumed there was a consultation in progress. Sr Mami (nurse at the clinic) opens the door at 17:56 however there was no patient in the room so she was obviously in a call. The first question she asked was if I have an appointment and I informed her that I tried to call twice during the day however it just rang without an answer. She then tells me that the Clinic is closed and I asked her how that’s possible because the closing time is 17:00 and it was 16:57. She rudely said the clinic is closed and proceeded to close the door in my face. She was rude and her responses were filled with so much negative attitude. This is not the treatment you would expect from a medical professional more so in the Clicks store. I am very disappointed by the poor quality of service or lack thereof, the worst was when she abruptly closed the door in my face.
