Cancelation of old account

Good day

On the 17th of September 2022. I went to standard bank centurion to open a new account and for the old one to be closed. And the consultant was very helpful and she advised that by Wednesday. 21st of September she will communicate with me via email to cancel the old account. I never received an email. I work Monday to Saturdays and am not able to go to the bank again. I sent my husband with a consent letter to collect my new card and also to terminate my old account as the consultant at centurion never cancelled it. My husband was advised that I need to go to the bank myself to cancel the old account but I'm not able to get off work again. As I went there last week but the lady did not cancel the old account and I do not want to be debited for both accounts.
