Frustrated member

I am so so frustrated with my medical aid -i feel like i will end up in a mental institution since i am struggling for over a year to get them to pay from the correct benefits -my dear husband is on a oncology approved program and time and again they make the same error of paying oncologists from my day to day funds and it takes forever to correct -if they even -correct it at all, i am so anxious that i cannot bear this situation anymore- are'nt they supposed to be trained in their jobs ??? This medical aid was one of the best a few years ago.
