Poor service recieved

I am so disappointed with the service with Alexandra Forbes .I spoke with the broker because of the problem I have with my medical account which he promised to help me with the matter and now he contact me and told me that he cannot resolve the matter I am having. City Hospital said I owned them R1572.40 because my medical aid won't be covering the cost of the procedure that was performed on me. So there were in contact with the hospital and they came back to me informing me that the hospital have sent the wrong codes that why Discovery won't cover the cost then, I tried to get into contact with the hospital and I was informed that the code are correct then after some time I received a call again from the broker telling me that the doctor that performed the procedure has to make an authorisation so that the medical aid will pay which he did get back to me and let me know that the hospital have done so by sending me the emails that he spoke with a people from City Hospital. now I received an email from the broker telling me different story that discovery will only pay R338.99 and the rest will have to pay it because the R724.90 it for admin fee which I don't know how so cause the day I went to the hospital I paid an amount that the hospital said I should pay cause my medical aid won't cover for it since it an admin fee then another amounts of R847.50 I have to pay for the theatre fee per hour which it what he told me but I was not in theatre that day they did the procedure in casualty then I went home... kindly clarify this for me and clear my name as I feel that this is now negatively affecting my life since I have to give birth soon and I wont be able to do so when my name is not in a good state.
