Unable to Close my Standard Bank Account after repeated attempts.

I am unable to close my Standard Bank Business Account even after repeated written communication and telephone conversations with my "Bank Manager"?? The said Bank Manager confirmed that the account would be closed after the last transaction cleared the account, that was 10 days ago and repeated mails to him and the respective support teams. What does it take to release myself from this relationship? Nobody responds with the status or next steps to be taken. I am so pleased I choose to move to another bank, as this reconfirms why I am leaving. The final nail in the coffin.... Just No response!
