Getting the run around for auth. number

So on the 10th of April I requested hospital pre-authorisation online via the member site - only to receive an error message. So I called on the 13th of April and had to do a new request. I was advised that since I had only joined the scheme 01 March 2015, that my case had been referred to the underwriters - response in 48hrs or longer. Since then I have called everyday, received different excuses and then today I receive an call notifying me that my membership will be terminated because I failed to disclose my condition on my application form - to which I responded that I did and I also sent them the email with the completed application form that I had previously sent through...so what now? I am supposed to have the procedure done next week Wednesday...I am supposed to receive a response today but I won't hold my breath...After being highly recommended by a good friend, I am seriously questioning that Fedhealth is \Real Medical Aid"- very disappointed."""
