refusing authorisation

on monday I was very sick then I went to their network doctor,so the doctor drew blood and told me to come back for the results after 3 days as I was really sick and needing treatment,after 3days I went back to the doctor then momentum refused to give authorization saying i need to go c the doctor after 4 days,I mean do you really choose when you need urgent attention?on their terms on conditions it does not state that you can only c the doctor after every 4 days ,I'm going to leave this medical aid and I will spread the word
