Discovery doesn't treat their custimers fair.

Discovery doesn't treat their client fair. My wife is pregnent we got pre authorisation in March for the hospital using the Discovery mobile app. My wife has to go in tomorrow for a emergency c section. We just found out a day before that something went rong on the Discivery app and the hospital we want to use is not covered and have to pay R9000 upfront before my wife can be admitted. Discivery said sory we can't help you we need to escalate this and can guve feedback in 2 weeks time. Where must I get R9000 in less than 24 hours. Discovery don't care about their customers.
