ACCOUNT NOT SETTLED

So after numerous attempts to send letters of authorization to Discovery regarding my Life Fourways hospital stay, it has never been settled. I have been handed over without my knowledge and this is driving me nuts. I NEED THEIR CEO TO GIVE ME A PHONE CALL AND CLEARLY EXPLAIN TO ME HOW THIS CAME ABOUT, AND IF I GET A CALL FROM A CONSULTANT WE WILL HAVE SERIOUS ISSUES. DISCOVERY HEALTH IS NONSENSE, I AM NOT RECOMMENDING IT TO ANYBODY.
