What pre-authorisation???

Good day. I have requested pre-authorisation on the 5th November, for theater procedure on the 10th. I had to postpone the procedure, due to no pre-authorisation received, subsequently I received a letter that the authorization is pending. Ever since I made numerous inquiries on the progress. I was not by some miracle cured, I still need treatment. Eventually a response was received on the 10th December that I should obtain pre-authorisation from the pre-authorisation department. WOW! Back to square 1 !!! What about the reference number, letter and numerous email communication?? Oh, yes I am just a paying member. Perhaps I should omit to pay, certainly then I will receive some attention??? The year is on its last leg, hence I have to tap into next year's benefits, thanks to your appalling service. For future reference; one visits a doctor because you are in PAIN or SICK, not to have a casual chat, there is a MEDICAL reason . A pity one should stoop so low to file a complain. I really regret changing my medical aid!!!
