FNB - How can we NOT help you?

I have been struggling to close by FNB Checque account. Even though the bank advertises that you can close your account by means of: 1) Written letter to fnb@premier, 2) call call centre 3) use chat function on App or 4) go to the branch, the bank STILL forced me to go to the nearest branch. Before I visited the brach FNB confirmed in writing that my account is ready to be closed and I need to visit the branch. I went to Brackenfell branch on 28/12/2021 and was assisted by Lizelle. Lizelle confirmed that my account can't be closed and that she will have to send a request to another department. She promised to phone me back within 3 days to come back to the branch. She never called me back. I went back to the branch on 08/01/2022 and was assisted by another consultant and the manager on duty. They explained that the consultant (Lizelle) is off-duty due to sickness and they can help me because all the information is locked on her computer. Again, I left the branch without being assisted. Most pathetic service from FNB as a whole and the Brackenfell branch who is unable to assist and unable to deliver on promises made. I want my account to be closed effective from my Original request.
