Hospital mistreatment

I was admired on the 2nd July 2020 at that hospital and I was not happy with their service. To begin with before you see a doctor you must pay levy of 200 up and for xray 350 for CT SCAN they firstly wanted 1800 which I refused to pay then they told me they will give me 50% discount which amounted to 800. I pay all these money cos I was desperate for help in pains on top of that they are still making claims on my medical aid. Now I am getting messages about outstanding money. After all the money I paid and medical aid. Even going for check up you still pay. That hospital needs to be checked cos everyone I whose been there they are complaining about the same problem.
