Disappointing service delivery from discovery

Sent a request for specialist authorisation, it is now day 6 with no response. I pay such a high premium for medical aid and hardly ever use use my benefits but for a simple thing as a specialist visit which is part of my benefit I need thousands of reasons to prove I need to see a specialist, thought I am entitled to it since it's part of my plan. I have to keep contacting them for feedback, terrible service.
