Overcharging and *****ing funds

Netcare Greenacres Hospital ripoff!! Paid cash for C section - 3 days paid upfront for maternity ward. Didnt even stay for 2 full days and they charged me for 3 full days. If i havent been discharged they would have charged me an extra day!! Total ripoff overcharging people and handing bill to settle without prior notification. Claiming that if you get admitted at 11h30pm you are liable for a whole day even if there is only 30min left for a day....
