Unhappy

I have been calling for the past 2weeks for an authorization number and to inform medical aid scheme that the network hospital does not have the specialist that I need and no hospital is willing to help me with the 40% Co payment. I undastand that using a non network hospital will require a co payment but now the problem is my network does not have the specialist that I need. I'm really not happy with the treatment that I getting from the medical aid, they keep promising to call me etc they never call back. I'm really disappointed in the treatment and will never recommend anyone to use this medical aid
