Chronic benefit not paid

I have been on some chronic medication for almost 20 years. Over the years additional chronic conditions needed additional chronic medications. Most of these were added to the chronic medication benefit. During 2021 I queried why some of the medication was not on chronic benefit. I was informed that the plan I was on did not cover those medications and if I upgraded to a better plan it would be covered. So in November 2021 I changed to a better plan which then started in January. When I went to get my chronic medication at the end of January 2022, suddenly NONE of my medication was paid from my chronic benefit. When phoning the medical aid they said I have to send a new script that listed everything as chronic. I NEVER had to do that! Then they changed their story to that DisChem had to indicate that the medication was chronic! How can a chemist dicatate to a medical aid that medication must be on a chronic benefit? That is rediculous! But rhis just shows the incomperence of the people working for Discovery!
