Bad service and no proper feedback

I app**** for a personal loan on the 11/11/2019 the application was apparently approved. I called on 14/11/2019 because i am getting no response and the response i got was there is a technical issue with my application. What technical issue?? When will i receive payment i urgently need the loan to fix my car. Why is nobody giving me any feedback why di i have to followup i have been with nedbank for years but now feel i need to move on to another bank.
