Attitude of time-wasters and uselessness

Extremely disappointed by attitude of employees of FNB. On the 28-Dec-2019 I made a transfer to my credit card covering what was due for debit order due on the 30th. At the time of transfer there was no indication of debit order taking place. On the 29-Dec I saw that despite of my transfer the debit order reflected on the credit card account. Contacted the bank via FNB app- secure chat and was told they can't stop the debit order, because I should have made the transfer 5 days before due date. I lodged a complaint asking the bank to reverse the penalty of R120 for unpaid debit order of my cheque account. The repply of Natasha Adolph is 'We cannot reverse unpaid fee as the Auto payment and the Payment you made was on the same day'- which is not true as I sent her a notification of transfer dated 28-Dec-2019. According to her 'To prevent the Auto payment from going off you need to make the transfer THREE working days before the payment due date'. This is a tumb-sucked argument. One says 5, another says 3. It is not a first time I transfer money to my credit card the day before the transfer. This is a typical attitude of time-wasters and useless employees, which I often encounter in the interaction with my bank.
