Chronic Meds not covered

As loyal medical aid clients we pay our monthly premiums with the hope that if anything unforseen should happen to us we will have our Medical Aid provider step in during our time if need. I was recently diagnosed with a chronic condition and my Dr a heart surgeon duly completed all documentation with the blood results. Discovery is only covering R75 out of a total monthly bill of R440 for this chronic medication. Come on Discovery Trustees. Treat your members fairly and don't give them bull**** cover on their claims.
