Nedbank Personal Loan Closure - Urgent support required.

I contacted the Nedbank call centre in excess of 5 time to:1. Obtain confirmation that my personal loan has been paid up in full and 2. That the account is closed. This included a visit to Nedbank Clearwater branch. I have spoken to 2 consultants today and tried to call the branch. Nedbank clearwater telephone number:- t +27 (0)11 *** is not in service. I am currently on call for 25 minutes - I have spoken to 2 people today. At least the branch confirmed that the payment would reflect, and 1 of the consultants today has confirmed that the account is paid up. As I have been transferred to a department where no-body has answered the phone now I am at my wits end. Please get in touch @*** to close the account and provide proof thereof.
