Disgusted in Fedhealth

So despite numerous emails and phone calls to try and resolve a matter of urgency Fedhealth just does not bother to get back to me. My kids and I currently does not have Medical Aid due to your mistake and I am not able to go to another service provider either as you are blocking me this after me removing my kids from Momentum Health believing that all was in order and we would be adequately covered. Your accounts department can often call me regarding payment but 3 months down the line no one bothers getting back to me to fix the mess that you made and the risk you have placed my kids under.
