Standard bank teller ignorance

Hellow Peter I have an issue with Standard Bank; I terminated my account with them in Mall Africa a long time ago, maybe in 2022 or 2021. To my surprise, on July 4, 2024, I received a payment from SARS using my old Standard bank account, along with a notification informing me of the amount I owed. Ignored the message since, deep down, I knew that I no longer had a regular bank account. When I called SARS, they paid, and when I went to the bank today, they informed me that they couldn't help me and that I needed to go to the Mall of Africa to reach the person who had assisted me previously. Please assist. My information is as follows: Name: Shadrack Thabang Moatshe ID:*** Email: *** Regards Thabang
