Scheming medical sheme

I recently went to my GP where I discussed a medical procedure and he referred me to a specialist. This is my first time ever in over 6 years since joining the medical aid that I have been referred to a specialist and was unaware that I have to obtain "authorisation" before I can consult with the specialist. Long story short the specialist agreed to do the procedure and all necessary hospital authorizations and approvals were obtained. The procedure was done and upon my discharge from hospital I receive a statement from the specialist advising that bonitas refused to pay the initial consultation fee as I did not have authorisation.

Another claim they refused to pay - I recently went for blood tests at Cuyler Hospital in Uitenhage on instruction from my GP. It was a quick in-and-out and all blood samples were taken in under 5 minutes. 2 weeks later I receive a statement from the pathologist where bonitas rejected to pay part of the claim - reason "due to the tests was not done in-hospital". Well the tests were all done inside the hospital. My understanding is that I first had to get hospital authorisation, be admitted to hospital and then do the test while I'm a patient in the hospital. Where is the logic in that?
