Discovery moving the goalposts in abdicating their responsibility,

I went for some medical tests a while back, performed by a physician. Based on the results of the extensive tests performed, Ozempic was prescribed as a chronic medication amongst other meds. Discovery did not approve the Ozempic, stating that they will only approve the medication as chronic once my fasting glucose count is above 7, i.e. when I am officially a diabetic. I am sure that we could have prevented getting to an officially diagnosed diabetic, had the Ozempic been approved. So now in January 2025, I went for my six-monthly checkup, and it turned out that my fasting glucose count is now above 7 (It is my opinion that this may have been avoided, had Discovery allowed the Ozempic at the time). So, my GP lodged a new application to put Ozempic on chronic. Discovery acknowledged that I am now diabetic, however the goalpost was moved by Discovery no want me to use alternative meds for three months before they will re-consider Ozempic. I have used alternative meds for the problem before, which obviously did not help. Discovery has access to my profile and should have been able to pick this up. Moreover, I am not comfortable to not take up the treatment, now prescribed by two medical professionals (Physician and General Practitioner) because Discovery is abdicating their responsibility. The problem now is that Discovery will not re-consider the application because I am now using Ozempic at my own cost in the meantime. So, for me, the clear message from discovery is that they are absolutely undermining the professionalism and qualification of the medical practitioners. I am highly irritated and disappointed with Discovery and the service and integrity I am getting from Discovery in exchange for a fortune I am paying on a monthly basis and have been doing for many years:-(
