2023 preauthorisation cannot be processed due to scheme changes not being finalised!!!!! HOW?????

As a new client, I was previously with the state medical aid, I am shocked by what I have to deal with. In November 2022, both my children were referred to surgery by our ENT. He asked to book for 10/01/2023 and phone for pre-authorisation to pre-book beds due to limited surgeries and beds available. Imagine my disgust when I am informed that this can only be submitted in 2023 due to YOU not finalizing scheme changes... I have never heard of this with other companies. This means I have to submit again on the 3rd of January and hopefully be able to book the beds for the 10th!!! You don't give much breathing space!!! I am rethinking my future pregnancy and your cover due to this ******* rule you have in place. So if my children are unable to have their surgeries, I guess it's no worry to you. Surely you can do better, this is not acceptable!
