Bias Treatment by Discovery

I am very perturb, infuriated and annoyed.I went to my ENT specialist yesterday at Flora Life Clinic Hospital who gave me a letter for admission at the same hospital. When I got to reception I was assisted by a consultant who went to go fetch Ntswaki Ngweru (Discovery Benefits Specialist) before he opened a file for me. I asked why is Ntswaki from Discovery being called as I am a Bankmed member and all he has to do is call Bankmed with the ICD code for an authorisation number. Ntswaki said that for me to be admitted she needs a diagnosis report as she decides the duration as a Discovery benefit nurse and I kept say that Bankmed needs the ICD codes from the doctor. She never took consideration of anything I was saying and was very BIAS towards me. She called my doctor who is a specialist/ surgeon and TOLD him that she as a benefits nurse is only giving me 2 day admission. Ntswaki feels firmly that she has authority over my health and my ENT's decision for admission. I called Bankmed and I also have chat proof that Discovery and Ntswaki from Discovery has no authority to decide if I should be admitted or not and also has no authority to make decisions for Bankmed members. Ntswaki has loaded details on the system that with her higher power of being a benefits nurse from Discovery and not Bankmed, she has control over my health and has right to decide how long I should be admitted by only grating 2 days admission so now if the doctor needs more days for observation, he will need to send a motivation to Discovery while I am a Bankmed member all because of Ntswaki's powers. This is such an inconvenience to my health and the doctors time. Can the 2 days be removed and let My Specialist be the one to decide on the duration.
