Discovery medical what a dissappoointment

I have been with Discovery comprehensive Classic for over 7 years due to having a chronic disease Rheumatoid Arthritis. I have never had an issue with them until this month when suddenly i had to pay for chronic medication!!!!!!! Then to top it all medication that i have been srinking for years is suddenly not allowed and must be prescribed by a physciatrist. I refuse to pay for my medication so when i land up in hospital due to the fact that i cannot move from pain, then it is going to cost them triple....
