Rude consultant, with autocratic and oppressive systems

I chose self transfer for my credit card payment upon application, not debit order. Consulted phones me regarding arrears, I make an advance to make payment on or before month end. Counters my advance, that the bank will automatically debit my account. States that she will put a note that no arrangement is made and drops the call on me. What it means that Capitec is an autocratic bank, bank debit is subject to account authorisation by account holder. And whereby I was pledging compliance in settling my dues.
