Bad Service for Chronic Patient

I am a Discovery Medical aid member for almost 2 years now and never have I been so unhappy about a claim made. I saw my GP last year, was sent for tests, only to find out I am insulin resistant, app**** for chronic meds, it was declined by medical aid, left it there. Now this year in Sept I went back to my GP, sent for tests, only to find out that I am now Diabetic type 2 and Hypertensive. Chronic medication was app**** for and was approved, but only to find out thst the GP visit and tests should be paid from the Chronic Illness Benefit and not from my Medical Savings. I called in to have this reviewed, only to find out that my GP's secretary completed the forms incorrectly, so this was rectified and a motivational letter was also attached from my GP, stating the diagnosis was only done now in Sept 2020, still they are declining to pay from the Chronic Illness benefit, now my question is, why do you offer to pay for GP visit and tests for NEW CHRONIC condition and when requested by client, it isnt granted? I am so frustrated and upset with Discovery, I have no words....
