Pathetic Service from Discovery Health

I am extremely disappointed with the pathetic service i have been receiving from Discovery. My mum was extremely sick and was getting seizures on the 24 Dec 2020 and no hospitals in KZN had beds due to the 2nd wave of covid. The only hospital available was alliance care that took my mum in to stabilize her. Unfortunately for us, Alliance for some reason did not get authorisation when my mum was admitted. However since then they have submitted all docs requested by discovery. My mum has been extremely sick since then and was in and out of hospital from Jan and passed away in Feb. I have been following up on this claim of R6 974.60 since then with various consultants/ mails. I call and have been kept holing for over 30 to 45 minutes at a time and eventually get cut off. I need resolution on this claim ASAP as i dont think it takes 5 months for it to be resolved.
