Discovery Health - BAD service - waiting for authorisation

Actially NO STARS!!! This is the second time I am reporting bad service from Discovery Health. The only time I had any response was when I complained on Hello Peter. Consultant phoned and asked for resend of authorisation request, which I did, STILL NO AUTHORISATION NUMBER, it has now been 2 weeks. What has happened to the 42 hr response time for an auth number???? Reference number ********** 643 received on the 17th of April. My appointment is next week for gastroscopy and still NO AUTHORISATION NUMBER. Pathetic service.
