Nonsense of a medical aid

I am disappointed to say the least. There's a doctors claim of R1800 which Malcor has not paid. How can i pay an amount like this when I'm on plan B? You people have been telling me that you investigating, the agents has not called me back like they said they would. I have followed up yesterday on a claim that was made in February. Why should i pay for medical aid? Your service is ****.
