Bad customer service

I am currently pregnant and was advised that I can register for a pregnancy program where I will have 8 Gynecologist visits and scan, blood test and other benefits that would not be charged on my savings as I am on the classic saver plan. I tried to register on the website and the and I could load my Dr as my Gynecologist of choice and he is under the Discovery network mind you, I was told by the call center and i.t department that my gynecologist is using a group practice number however he has confirmed that it is indeed his practice number. I called discovery to advise that as per my gynecologist the practice number is correct I was than transferred to the authorization department and the gentleman i spoke to advised that he had loaded my gynecologist of choice, however thew first appointment I had with my gynecologist and blood tests for January which was on the 09/01/2017 was billed on my savings. this is not on and needs to be rectified as by the time I am ready to give birth I will nolonger have any funds on my medical aid which caters for me and my daughter. Please resolve the matter asap.
