NO Feedback after a month

On the 8 Dec 2018 we went to Nedbank Woodlands to close all accounts due to Immigration. We were told to phone the credit card devision which we did. After 30 min no answer we left. Thuli phoned me 30 min later to tell me I need to pay R15 Into my credit card and it will be closed. Up to today no feedback. My husband went in again on the 10 Dec. The 12 Dec Timothy Links responded via mail that the card will be closed once all transactions were finalized. On the 20 Dec we followed up if indeed both our Credit cards were closed and if our online profiles were closed. Up till today No response. We are in Canada for a month now and we would really like this matter resolved and finalized.
