Very disappointed, pre authorisation not approved!!

If I could I would give a zero rating. I called the for pre authorisation for admission by my doctor. Initially I gave them what the doctor wrote to admission reception, i did not at that point have the codes, the reception also did not have the code and had to call the doctor. When i called again for pre authorisation after getting the feedback from the doctor still it was not good enough and they told the receptionest I must go to emergency, they've approved my claim for emergency. Mind you I've been at emergency with this issue and was not assisted and on top of that had to pay thousands out of my pocket. I called back again to undestand why the pre authorisation can not be approved and was told the consultant that i spoke to before wrote a note that I cannot be treated for pain relief. So now my question is what type of medical treatment am I supposed to get, or do I pay this health insurance so that I must do my own treatment at home? This is really disappointing, where am I suppose to get medical treatment if I can't use Oneplan. I spoke to 3 consultants. The first one I don't remember their name, the other two is Kefiloe Mannathoko and Nthabiseng Vega
