Standard Bank is dysfunctional

My account was cancelled in October of last year. I recieved the confirmation letter of my account closure and that all cards I have should be destroyed as soon as possible which I did. The confirmation letter confirmed I do not owe the bank any money however, since November 2022 I have started receiving statements suggesting I owe the bank money. When I confronted the bank about this in December, they said by January I would recieve feedback but no feedback was receieved.

I am still receiving this statement so I called again middle of last week to see what the story is and insisting I have my letter confirmation closure of my account. The agent promised me that all charges would be reversed and that I would recieve a letter confirming this on Friday, 10 February 2023. I am still yet to recieve this letter.

I then called again today, 13 Februay 2023 to see where this letter is and have had two agents, the latest being a lady by the name of Thabisa, transfer me to a survey instead of assisting me with this issue.

If this issue is not resolved followed by a call by a senior member of staff, I will have no option but to lodge a complaint to the Ombudsman. All the calls with agents have been recorded so I do not worry about the outcome.
