Discovery really disappointed again

I'm so disappointed with discovery key care as I've had a brain operation just to find out they don't cover. Before I went for the operation. There is a reason for having a medical aid, I don't go to a hospital because I want to but it's a need. On the 13th of June I had an operation and was seen by the only Dr. In the Western Cape of this speciality, recovery from this take extremely long meaning I will be out of action for a very long time. Meaning I cannot work. Up till today I'm struggling with their team to clear payments for the specialist's that did this operation. This is the second time I'm having this issue and it's really frustrating as no one asks to get sick. I'm sitting with Dr's bills way above what I can afford but have a medical aid. Being boarded from work makes it even more difficult and frustrating. I've spent lots of money on calling them just to Everytime having to explain myself over and over they expect the patient to know the ICD 10 codings and procedures making this whole process sporadic. When your ill or recovering this should not be an issue as a medical aid should be there to take u by the hand and assist. There's such alot of products that doesn't get explained to u. Hence such alot of people if they hear discovery walk away. If u don't get ill they will easily take your funds but just get sick and see how u are treated. They don't care if u get lawsuits from Dr's bills. This is after sending the documentation they requested.
