Long wait for hospital authorisation

I am waiting for urgent hospital authorisation from discovery health. They received the relevant supporting documents which was requested. Now they say they have to listen to the recordings when member joined the medical aid which will take another 4 to 10 working days. Hospital admission is booked for the 20th and it is urgent. So it's ok if the patient dies during this waiting time. These conditions that are now being stipulated was not stated when joining. There are no waiting periods. I will appreciate if this could be done faster please. I am with discovery all my life and this is the first bad experience I have had. I am very disappointed.
