Medical aid not covering thier commitments

Been a member at Discovery for 29 years. God knows why..... My wife was diagnosed with glioblastoma (Brain cancer) 2 years ago. We did the radiation and chemo which basically did nothing other than enriched the oncologists to the tune of R500 000-00. Discovery paid some of this but then the "allocation" ran out. So basically we are on a wait and see until you pass away medical care. Discovery stopped paying All costs in June last year. I went to Discoverys ostentatious offices in Sandton as I could not understand my service providers were claiming that Discovery was telling them they had paid their contribution to me but I had not received a cent from Discovery. When I arrived at their offices I was directed to a room of other disgruntled customers and handed a phone. There I sat for 3,5 hours on the phone while I was transferred from department to department and to date still have absolutely no idea where I stand. Discovery will tell you they will pay R 500 00-00 towards Oncology treatment. However in our case Oncologists can not do anything. Hence we dont qualify for any cancer benefits despite been diagnosed with cancer and waiting to pass away. We were registered with AIB (Advanced Illness Benefits) but hey thats only for a year then you must reapply. Surely as discovery is a medial aid they should know the brain cancer my wife has is 90% incurable!!!!! They the pharmacy is not been paid for her medication as it was not listed as Chronic. Gap cover wont pay because we are not in hospital. Discovery did send me a 6 page list of codes and medical terms and expect me as a lay [person to understand what is going on. As a customer you will NEVER receive a phone call or any feedback. As a customer you are expected to troll through their website which throws Insurance and banking info at you rather than medical aid info and then you are expected to make sense of what is going on. They have totally removed themselves from their customers and duclk and dive between departments to avoid standing by their service or cover. THE WORST EXPERIENCE YOU CAN IMAGINE ALL WHILE WATCHING YOUR LOVED ON SLOWLY LOOSE LIFE. THANKS DISCOVERY!
