Discovery Keycare Authorization a Mess

This is the 2nd time that i had to struggle getting an authorization code to see a specialist. Even after the specialist spoke to Discovery stating it was an urgent matter, Discovery still just told the specialist that a letter or form must be filled in, signed by the specialist and then be sent to Discovery and after they received the form it may take up to 8 hours to receive an authorization code. Really considering moving to another medical aid.
