Two weeks and still no authorization number

I joined momentum after being with discovery. There was no exclusion period and we were informed that we had cover immediately. During the second week of February I developed pain in my kidney and went to my GP who then referred me to a specialist. The specialist then told me I needed to go for a scope the following Monday (15/2/2016) I saw him on the 10th of Feb. I notified the medical aid and requested an authorisation number. They told me that they needed to do a clinical check which would take 48hours. On Monday morning when I was scheduled to go into theatre I had no authorization number and absolutely NO feedback. After calling back and forth I found out they hadn't received the clinical reports so I visited each doctor myself and they told me they never received forms. My procedure had to be postponed to Monday 22 February as I had no authorization number. After wasting a day off work I'm sure you can understand how frustrated I was. To this day I am STILL waiting for my authorization number and I am due to go into theatre on Monday. I regret leaving discovery and will NEVER recommend momentum! To anyone. Feedback would be greatly appreciated as I am in constant pain!!
