Discovery Health making me sick

I have been trying for a week and a half to make contact with ANYONE at Discovery to follow up on two invoices they incorrectly declined and still have not corrected. Either the telephone numbers go to a voice info system which says "the number you have dialed does not exist" ????? Or it rings and just ends call... if I log onto the website and try a chat I am 40th inline and have to wait for 58 minutes - I tried to out of desperation but at 14 minutes the chat ended my session as I had been inactive too long ???????????? What if it's an emergency ? Seriously Discovery ??? Not only was your bank noted worst on a survey for client services but now your medical aid has NO service ? You are a large player and there is simply no excuse.
