Problems with Medical Aid

I have been with Momentum Health for a few years now. I moved to another option in January 2015. I moved from the student option to the Access option (which is quite expensive so you want service delivery). I though everything was done. I received a few medical aid cards since February (after I had to e-mail them to ask for a new medical aid card). I received two different options cards, so I called them and asked them what was happening. I found out that my option was never changed to the Access option. I kept calling every month to make sure that my option is changed to the correct option, only to find out that my medical aid is still not sorted out! I am on the pregnancy program and I am scared that I will get surprises with my c-section bill. A medical aid is suppose to make you feel calm and taken care of! My medical aid is sorted out now, but now I received a bill from my doctors saying the medical aid only paid for one 2D scan. The pregnancy program allows 2x 2D scans and 4 GP visits. Now I had to mail the medical aid again to find out what is happening. I did not even receive a letter from the medical aid saying why or what they paid and did not pay. Pathetic!
