Medicare Hospital Rustenburg - Terrible service

I am a private patient who paid cash for medical services at Medicare Rustenburg. This was around the middle of April 2022, after my medical treatment, I was then provided a statement that showed there was a credit amount of just over R7000. I provided my banking details & to date, I have not received any replies to the 4 emails I have sent so far. I was dealing with Sharon from the finance department who ignores my emails. This kind of customer care is just terrible & I would recommend anyone who needs medical care to rather Opt for their treatment in Pretoria or Johannesburg where you are guaranteed better service.
