Son's hospitalisation delayed indefinitely

My son is covered in his father's Discovery Medical Aid. He was diagnosed with tonsilitis on 4th August 2015 and on the same day his GP sent a hospitalisation authorisation to Discovery. No response was received until I sent another request on the 1st of September. I have since received one email (after three weeks of lodging my request) but still no authorisation. How is my son to survive the pain of a sore throat with swollen tonsils???? What is the purpose of health insurance if one has to wait two whole months for hospitalisation authorisation???? THIS IS NOT ACCEPTABLE
