I app**** for a personal loan on the nedbank application. Received an sms that it was provisionally approved and needed to submit documents to the nearest branch. I submitted all documents required & signed the application at Mall of Africa on Friday 27th October 2017. To date I have not received a response, the consultant at Mall of Africa said he doesn't have access to processing the application because it was done online using the Nedbank application. He also said when he tried follow up he was told that the person assigned to it hasn't got confirmation from my bank. Mind you I bank with NEDBANK. How does it become difficult to get confirmation for a Nedbank Loan from Nedbank? Pathetic service!
