No feedback in a week

I was admitted to hospital last week Tuesday (10-Nov-15), I was discharged the 11-Nov. I needed to do a follow up with my doctor this Wednesday that passed (18-Nov) but I called in on Monday already (16-Nov) to get authorization to see him. I made numerous calls to Discovery to follow up, they said to me it takes anything from 8 to 16 hours which has long passed. I called in on Tuesday & this morning, the consultants that are helping have no idea why my authorization is still waiting to be approved. I was told there are no back logs & I have enough funds in my \Specialist benefits". This is the first time I'm waiting so long for discovery to get back to me"
