Pensioners doing Discovery admin

Elderly people must do their admin. My father and mother who is 73 tested positive for Covid last year at the Wilgeheuwel hospital and is now being threatened by Lancet that they will take legal action. Their medical aid number is ***, my father has been up and down to the hospital to ask them to submit the correct code because Discovery will not pay because the code is incorrect. WHY?? not deal with the doctor who submitted the claim discovery and not the members. My fathers name is Charles Smith and his contact number is *** if you are interested in fixing this mess Discovery.
