Worst Medical Aid company that does not care about their clients at all

It has taken me more than 6 months now to resolve a claim that Discovery keep telling me is covered under my plan, but they keep coming back with more detail they require to pay out the claim. It really feels like it is currently a game of attrition where Discovery looks for every reason in the book to not pay out the claim in the hope that I will lose motivation and stop trying. I have been sent from one person to the next and everyone says I should be paid out, but to get paid out I need to do x, y, z. Just for me to do x,y z and then be told that I slit need to do more and it is never-ending. I also have to speak to a new person every time I follow up which means I need to go through the entire ordeal over and over. This is the absolute worst service I have received and not even logging a complaint with their complaints department even got a response. Discovery is all about taking customers' money and doing everything in their power to not deliver a service and making it close to impossible to get issues resolved.
