Worst Medical Aid Ever!

I am quite disappointed as I thought changing my medical aid to LA Health which is administered by Discovery will be a better option. I have been on treatment for a chronic condition and have been on the same meds for the past 13 years only to find out that LA Health does not pay for the full costs of these meds and treatment. My previous medical aid has covered all costs relating to my chronic condition. LA Health wants my doctor to now change my meds to something else which they pay for after I have been on the same meds and have had no medical issues since I was diagnosed with my condition. Or I must pay two thirds of the cost of the medication. I find it frustrating as I now need to see how my body responds to the new medication as I am not in a position to afford these costs and I am also paying for a medical aid that doesn't cover these costs. I should have rather not switched medical aids had I known this was to happen. Now I have to wait a whole year again to change back to my previous medical aid.
