Claim unfairly declined

On the 5th of November 2017 i had an emergency and had to check myself into Unitas Hospital in Centurion due to the fact that no GP's open on Sunday afternoon unless per appointment. When i got to Unitas i was observed, blood tests taken and the Doctor gave me medication and sent me home because after the examination they found that i wasn't critical and that i just had a kidney/bladder infection. The doctor at Unitas however said i need to do further scans eg x-ray and radioscan which are covered by my medical aid. I got booked for Tuesday the 7th but couldnt make it and rescheduled for the 9th due to work commitments. So now i just recently received a bill from the Drs Burger Radiologists Inc saying my medical aid disputed their claim. I followed up with my medical aid today 21/11/2017 to find out why the claim was declined as my med aid covers radiology as well only to be told by a very rude lady that i was supposed to get authorisation from my medical aid first before doing further tests. I asked the lady how do i get authorisation if i am in a panic state and peeing thick blood the whole morning. She than responded by telling me that i was supposed to wait for Monday to get authorisation.

What kind of ethic is that when a person believes their life is at stake and they have to wait for the next day to get assistance simply because Bonitas is not open on Sunday for authorisations, and to add onto that which steps did Bonitas take to make sure that a person knows that they need to get authorisation during a life threatening situation?? Even the Dr's assistants nor the Dr's said anything about getting authorisation. So now i follow the Dr's orders and do further examinations and Bonitas just declines the claim simply because authorisation wasnt requested. Who's negligence is it if i wasnt informed by the Dr or Bonitas that authorisation is needed first? And what kind of nonsense is it that when a person has an emergency they need to wait for Monday?? This is utter B*s...And if someone doesnt get back to me regarding this issue i am cancelling my membership and im gonna make sure that the media and nation know what kind of mickey mouse organisation Bonitas is. I am not a Doctor by profession to diagnose the severity of my illness and i doubt any human being has time to read through a whole list of procedures that need authorisation when they are bleeding to death and feeling weak.
