Cancellation of a debit and reversal

went to your Woodmead branch today to cancel a debit i had with a liquidated/closed company. the branch indicated that they cant assist me with the cancellation they tell me to go to the liquidated company i ask how because the facility is closed. i mean as a client shouldn't they protect me? Now here is a classic the lady advises me the solution is for me to close the acc. and open a new one but first I must bring proof of res and id. I then ask how do they verify that im the current holder of the account. They have my credential and the biometric finger confirmed. the lady indicated that they don't keep records of clients after opening account REALLY, then it means Capitec is not trustworthy. What do they do to our valuable documents. This matter needs serious attention.

I left the branch livid and out of words.
