Discovery incompetence strikes again!

During the entire DEcember 2017 I tried to get help from Discovery as everytime I tried to fill a prescription I was told by the pharmacy that it shows error I have to contact my medical aid. So I had to pay for medication out of my own pocket and can't get a refund from Discovery.

Then in January I did not have enough money in my account, but paid my medical aid manually. Then I got an sms from discovery I short paid with R600 I then paid R1000 to Discovery. A week later I again tried to fil l a prescription and yet again I was told by pharmacy that I have to contact my medical aid error appears on their system.

I tried contacting *********** medical aid and phone was put down in my ear.

Where and to whom can I speak to get a refund for all the prescriptions I paid because of these errors and to unsuspend my medical aid. Or must I move to a more competent medical aid.
