Sold a not work medical aid plan

I have been sold a policy. And the policy is not working for me. I have been told that i have unlimited doctors visits under Essential Dynamic Smart. My daughter which is a depandant got sick twice in a space of two months and took the child to the doctor and the doctor told me the plan is not work. That was the first visit and had to pay cash. The second time was last week and my daughter got injured at school and took the child to a different doctor and she told me the same thing, and on both occsssions i had to pay cash when i am i am paying R3400 monthly on medical aid. What services am i paying for when i cant use the medical aid. I got a call from one lady from Discovery on Monday and she told me shes phoning in regards the payment which i reversed from the previous month and she told me she hoping to debit the acount. Exactly what am i paying for in this case? I was not happy about the service. I feel like i am donating my money to Discovery Health. I would like them to pull the first call and send to me to listen and tell me why this plan is not used by many doctors when i was told otherwise.
