HOSPITALISATION AUTHORISED THEN DECLINED AFTER! BAD SERVICE FROM DISCOVERY HEALTH!

I was admitted at EmoyaMed Private hospital from 28June2021 - 01 July2021. The hospital called Discovery health for authorisation and eventually hours after waiting they gave authorisation. I’ve just noted that Discovery health sent me an email on the 02July2021 saying that they’ve declined my hospitalisation but I have an authorisation number from them which is confusing. I’ve also noted that the hospital was paid off my savings instead of my hospital plan. The worst part is that when you try calling them you hold for a very long time and ultimately get no assistance!!!! The confusing part is that they gave authorisation but after hospitalisation they send an email saying they declined. Please give me answers Discovery health, I’m on Classic saver
