Failure to close my accounts

I'm a client of Absa. Since November 2025 I requested that they close my trust account to date which is February 2026 same is not done. I no longer need those accounts because I am no longer in practice. The accounts keep incurring charges which I am expected to pay which is truly unfair. My banker is also not being of assistance. At first she gave me wrong procedure to follow which I followed. Then someone else came and told me to do something different. I don't know what to do anymore to get Absa to close my business account and trust account. My banker is aware that I am no longer in practice as I have communicated same to her. Absa please close my accounts.
