Fedhealth Medical Aid services- very bad

I was admitted to Hospital for what i thought was abdominal pains, it was terrible, Dr's did all kinds of tests and came to conclusion that that pain is actually from my back. Dr explained to me cause pain was so severe that i did not note it was from my back, as it started to effected my legs. I fell a few times as my left leg sometimes did not want to move. The neurosurgery found that there is a problem in my spine. We requested autherization from Fedhealth for the surgery to be done, which was supposed to done on Tuesday 24 January, but to my surprise, they denied the autherization as I'm not "covered" for the operation. There was no proper communication done, i had to call all the time, and when i checked on the Family Room to track the progress of the autherization, i saw that it was DENIED. My arguement is i'm in desperate need of medical help, as i have to endure this terrible pain every day, it effects my children as well to see their mother suffering like this. When i called yesterday, 25th January, the one consultant asked me, mam why didnt you chose a higher plan..LOL..i mean now really, a single mom with 2 kids, a higher plan. That would cost me half my salary, i mean this in a very way...I really need help please. The medication i have given is TRAMADOL 50MG, SYNALEVE CAPSULES, VIMOVO 500/20MG, EXINEF 90MG, NUBACAP 75MG & ZOFER RAPITAB 4MG- This tablet is for the nausea as the tablets is too strong. Those who know tablets, this is what i live on now. my apetite is gone, i eat fruit only. All these tablets make me drowsy like a zombie, but the pain stays there. I cant sit up straight for a long time, i cant walk long distances, so basically i cant enjoy my life. Can someone please call me with a solution to my problem please, i need this surgery to be done asap, i'm going to lose my job very soon. Fedhealth show some humaity towards your clients, and communicate in a effective way. Thank you God bless.
