Inability to sort out an account enquiry

I have been attempting to sort out an account from Eugene Marais Hospital since 18 June 2025. The matter was eventually escalated to an unknown individual and again all attempts to query the account disappears into a black hole of communication. The hospital was also attempting to claim for items that the medical aid responded were "non-chargeable items and the member is not liable". The accounts get sent out in record time but good luck querying or resolving anything.
