Momentum Health a pathetic medical aid.

I'm a member of the Momentum Health4Me medical insurance. I had been hearing through the g****vine, since I hadn't consulted using my membership card. However, I have now consulted and have firsthand information. One can only visit a limited number of GP. You also have to get authorisation. Upon my consultation with my pregnant wife, I discovered that GP's do not recommend using this pathetic medical aid and the GP I visited did not accept this medical aid and said that this medical aid does not pay for their services. The GP would not let my wife do a sonar through the medical aid since, it is "troublesome". I had to pay cash for the sonar. I want to leave this medical, and I wish I could get my money back, as it has been deducting my money for about 3 years now.
