Complete lack of Customer Service bad for health

I called before having a procedure done to determine exact cost and how payment would be made by the medical aid. I was given three options and chose the one that would not deplete my medical savings, &was assured, thrice by Natalia that it would come from my risk/hospital savings. I then had the procedure done in my Dr's rooms the following day, and claimed the amount from medical aid. To my 'surprise' the amount came off of my savings. I then called to query the information I was given and Roshaan told me i was given the incorrect information, she would listen to the call and get back to me. That was last Friday. The i called yesterday and Lamile concurred that I was given the incorrect information,and she apologised for no-one getting back to me, she would pull the call and get back to me today. It is 3pm now and still no call from Discovery. Sadly this is not the first and possibly not the last interaction I have had with this company where incorrect information is handed out for free to customers who believe that what they are being told is correct. Shame on you Discovery for playing with my savings and my time. Your lack of courtesy is pathetic!
