Unsatisfactory feedback received from netcare emergency service

I got sick at home November 2017 and my colleague called ER24 emergency service,so my medical aid told me that netcare is the one having to deal with the payment to ER so i sent an email to them regarding the issue,netcare severally refused to pay the bill and said i should pay myself so my question is why pay medical aid if by the time you need to use it they would pay.Now im sitting with a bill of R3000 that i need to pay of which instead of them giving me the right answer they are telling me that my issue was not an emergency,how come can it not be an emergency if i got admitted to the hospital the very same day.
