Medi Clinic Sandton causes my child to go into distress then tries to bill me for it!

My wife went into labour at medi clinic sandton, the anaesthetist who did her epidural was too busy trying to get me to sign his fee payment form to monitor what the medi clinic nurse was doing and when my wife started to lose consciousness i noticed that the nurse had put the epidural drugs into her arm instead of her back! My unborn child then started to go into distress which then caused us to have an emergency c section. So at our expense now as private patients we have to pay for the emergency ceasar due to their negligence. THEN they are threatening us with legal action because we apparently owe them for a day stayed which we did not stay! Absolutely appalling.
