Discovery Medical Aid is daylight *******!

I am on Discovery Essential Smart Plan. I recently got injured and went to the casualty ward in hospital. To my surprise when I got there I was told my plan doesn’t pay for X-rays as it is just a hospital plan. So I had to pay cash for that. 2 weeks later I have received more bills that discovery didn’t pay to the hospital nor the Dr’s at casualty ward.

My question is why did it not pay for anything yet the plan I have is a “hospital plan”. Why am I paying monthly yet I now have to fork out more money over and above my contributions ?

Looking to move to another medical aid cause I’ve never had such issues with Bestmed and Bonitas!
