FNB has terrible accibility

I have a debit order I cannot confirm that has gone off my account for several months for R500. I have tried disputing it a few times but it is over the app limit. It is such a round figure that it is not outside the realm of possibility that this could be a payment arrangement I had made. However, I should be able to get clear info from my bank to verify this.

When calling FNB, you hold for an eternity only to be given a different number and there appear to be no online resources to deal with this outside of calling a phone that puts you on hold so long that even the voice recording gets tired.

The debit order with the below reference has come up on my timelines and even on hello Peter as *****ulent and I need to be sure that the money I think I am paying towards my debt isn't going to *****sters. ALL YOU HAVE TO DO IS ANSWER YOUR PHONE!!!
