Pregnant and no specialist

I am currently 22 weeks pregnant. I contacted Bankmed 2 weeks ago as I found out my Gynocologist is not contracted with the medical aid. I requested a list of doctors that I am allowed to use, as I cannot afford to pay R15 000 out of pocket for a doctor. I have already registered at the network hospital that I am going to use, and explained this to the agent. After numerous fights over the phone, the agent called me back with 2 doctors, which after I called them, found out they are also not part of the network. I then wrote a complaint to the CEO line. Nazley responded with 4 doctors. 2 In Pretoria, and 1 in ALberton, and 1 in the area I was looking for. The 3 doctors out of my area, is more than an hours drive. The 1 doctor that they gave me is fully booked and secondly, not what I wanted. I was suppose to have a 20 week scan to do the last down sindrown testes. Which is rather difficult if you do not have a doctor. I rep**** to Nazley on Tuesday stating all this, and no reply from Bankmed. I have a high risk pregnancy, and I expect my medical aid to be there for me. As I told you before, If anything happens to me, I will hold you responsible. THIS IS CRACY!!!
