Waiting over a week to get Authorization

Seriously... I have been going back and forth to query what is my authorization number for an appointment with the specialist my dr referred me to, It has been over a week of being placed on hold and leaving messages and no one returns your call.....and nothing. My appointment is today at 3:30pm in Bellville and it is now 2:40pm. I am at work in Cape Town anxiously waiting for an sms to come through but nothing.... this is pathetic service, especially for it being my first time being referred to a specialist, for me to constantly be calling and sorting out issues between the person sending off my referral letter and the Discovery smses I have been receiving regarding the issues. This is really unacceptable that there is no communication between Discovery and the the receptionist at the doctor's offices regarding errors.... I am like the middle man bwtween the doctor's offices, the specialist's offices and Discovery. What are we paying for if we are doing their work to follow up.... yes I understand that it is my responsibility... but to a certain extent. I am very upset at the pathetic service and turnaround time. Does Discovery really care about our health? or just our money? :(
