Unjustified debit order

I requested a settlement quote at the branch for my access facility account. I was given the settlement amount by the consultant relying on the system. I immediately transferred the settlement amount into my access facility account in order to settle my debt. Both my banking app and bank system as shown by consultant vindicated that my debt has been settled and my account is up to date. Despite settling the debt I decided to keep my account for accessibility of required credit in the future.

To my surprise the bank later debited from my up to date account. I approached the branch to seek clarity and head office was contacted. No rational justification has been pointed out as I was told the matter is being looked into. The matter is yet to be resolved. The silence and lack of intervention from the bank is on steroids.

Currently I have no access to the account due to unjustifiable arrears and interests charges.

I am no longer interested in keeping the account and remaining with the bank as a client but I am genuinely held hostage.
