Medical Professionals with ethical concerns

I'm Nkosinathi Wela, father of Zwelonke.

Zwelonke was sick and need medical attention which Dr Matilda Madekurozwa(PMB) stated that the procedures he needs done can only be done in hospital and hi would have to be admitted and that this would only be overnight.

Early February 2020 he was admitted after having received the go ahead (authorization) from the medical aid, they performed some tests and the following day were told by the doctor that we would have to stay an additional because the anesthesiologist was not notified. at the end of the third day we were discharged from medclinic(PMB) and told that "we can go" our doctor wont make it because of the rain.

The bills started coming through and what was strange is that these bills were charging from my Medical Savings account(MSA) and not the unlimited inhospital cover, i was told about.

Me and my wife called the medical aid many times to get this resolved to no avail stating that the need a "treatment plan from the doctor" and the doctor has no clue what this treatment plan is.

The doctor is stating that the case manager or someone at the hospital put in a "F80.9 code instead of the G40.6 that she had put in". which makes no sense apart from the fact that the mistake is on someone else side. she did not fail to mention that once this happens i would have to foot the bill and there is no going back.

why did the hospital approve the stay only to double back and deny the claims.?

what assurance do i have that they cover any of the hospital stays that i will undergo in the future?

I refuse to believe that i personal have to pay an amount in excess of 30k for either: 1. Incompetence (no knowledge of what a treatment plan is), 2. Lack of due care (not being discharged by the actual doctor after a proper checkup) or 3. improper completion of documents by hospital staff.

I currently have a house full of sick kids and cant take them to any doctor because my MSA and limited day to day.
