Discovery call center and accounts department is so INCOMPETEND its actually scary

Discovery accounts and oncology department is the most ***********ly health care departments. My dad is 72 years terminal ill and with every doctors visit or blood test discovery got stories to settle the bill. They just take money from the savings and take months to do corrections. He is registered for oncology benefit but that seems that discovery doesn't care THEY JUST TAKE MONEY FROM SAVINGS. I am struggling with n reverse payment for longer than a month now and almost 4 hours on call center calls on my expense. They say its going to be resolved in 4 to 5 working days and when you follow up with reference numbers NOTHING has been done. This is the worst service ever but when end of the month comes you have to pay over R 12 000 for medical aid premium alone. I definitely NOT recommend Discover for medical aid. Relatives are with BONITAS with the same diagnosis but without any of this frustration. Discovery is welcome to give me a call and explain this situation ***
