Bad service

I've been in contact with Discovery since on Wednesday,all I need is an authorisation for a specialist, they told me there's missing info in the form that the GP needs to fill, I went back the GPs surgery to tell him so he filled in the info but still no success, this is the 1st time I need a specialist since i was a member in this medical aid but they are posting me left right and centre as if I don't pay on monthly basis, I'm so disappointed in the service i get and this happens in the most difficult time of my life and health, they have lost a customer in me.
