Credit card payment reversal

Fnb has incorrectly debited my cheque account with a debit order for minimum payment for my credit card.

I paid my credit card in full on the 25th. It is from a Fnb cheque card to an Fnb credit card.

I have always paid between the 25th and 37th of the month for years.

In the early hours of the morning of the 29th - a minimum payment was automatically debited.

I tried to phone to sort it out and get the money reversed and waited so long that i ran out of air time.

I then went onto the secure chat on the app and they came back that i am 1025 in the queue.... really FNB - is that good enough ?

This is beyond appalling service, i would like my debit order reversed please asap as i have orher commitments to pay.

Thank you Tanya ***
