Totally Disappointed

I have been with Discovery Medical Aid for over 25 years but was greatly disappointed with the outcome of my stay in hospital from the 19 May to the 31st May 2025. When you fall ill suddenly you expect the medical aid to take care of all your bills including your hospitalization and attending doctors. Unfortunately i was told that the attending doctors are not on the network and will not be paid 100% . I have the doctors hounding me daily for the part payments that were not not covered by the medical aid. What is the purpose of saying hospitalization is 100% when the doctors attending are not fully covered? Even my diagnoses of Primary Bi****y Cholangitis(PBC) chronic meds is not covered by DISCOVERY what is the purpose of such a medical aid? shouldn't they take into consideration the duration I have have been supporting them and analysis the situation before giving a patient more grief to deal with. totally disappointed in the process of looking for a medical aid that covers my needs.
