VERY VERY ANGRY CLIENT

I happen to have a big issue with my medical AID CAMAF ,on the 13/04/2018 my son fell and broke his wrist at around 7:00 pm in the evening and since i know that i have a medical aid i took him to GARDEN CITY hospital for assessment ,when we got there he was checked by a DR and he referred him to do x-rays and he confirmed that the wrist is broken he told the nurses put a cast on his wrist and gave us a script for his medication as well as the referral letter to see an Orthopedic for assessment, to my surprise when we got to the pharmacy they told us that the DR who gave us the script is not registered on our Netcare option so we have to pay cash ,what i know is that i have a medical aid for a reason because i cant afford to pay cash and Garden City is the Netcare hospital which i was told that i must go to always when there is an emergency ,i decided to call CAMAF today 16/04/2018 and was told by a consultant that the DR is not a netcare DR so i have to pay cash for the assessment and the x-rays where would i get that money from .....my question is how would i have known that the DR is not a Netcare DR if i was not told ,now i have to pay cash and i pay my medical aid monthly for the emergencies like the one that happended to my son .
