Disappointing Nedbank Service

I app**** for home loan with Nedbank under ref ********** 2 on the 14th of September 2017 which was approved on the 27th of September 2017 then later on the 6th of October I received a letter of termination under ref ********** without any further information or explanation .There was only an email address. I asked my banker at Sunward branch to assist with finding out the reason for reversal and she said reason could not be given and it is not a matter of further discussion. The banker gave me contact Centre number ‪ ********** 111‬ to call and find out (i thought banker is supposed to do this on my half, i pay R299 service fee every month for private banking). The contact Centre referred me back to my banker as she is the one who was supposed to find out and advise me of any reasons. I later realized there was an email address: ********** that was stated to contact for further information. I decided to send an email to find out reason and possible way forward. This was on the 10th of October, on the 20th of October i still had no response so i decided to call home loans customer service department ‪ ********** 589‬ and I was again advised not to do the follow up as my private banker is supposed to be doing and they said I should contact my bankers’ manager. I have been going back and forth and it seems no one will be able to assist. I just need to know if there is a specific reason and if there is a way forward to rectify the issue. My worry is ; 1. That I had secured the property and ran around to put up the deposit that they required and later on deal to be withdrawn 2. I know it is the Credit Provider right to withdraw application if they are not happy with anything and it is also my right to be informed of the exact reasons why they are withdrawing as I will have committed a lot of time and resources towards that. 3. I may lose the property if I take long to respond to the property owners. I have been working for my company for the past 9 years and i have a salary account with Nedbank. I have been a Nedbank client since 2013. I hope my bond will be reinstated and proceed to own my house. Very disappointed with Nedbank service!!!!
