FNB dissatisfied service. Horrible

Extremely unsatisfied with FNB. Got a notification that an eraly run for debit orders will be done on 15/12/2021. Got in touch with the team of bankers to make an arrangement to not do the early run on my accounts held with FNB as I will not be able to afford it. Today when i received my fort night pay the debit order was taken from 2 of my accounts. I went to the FNB Branch and they gave me a phone and connected me to the personal loan department to reverse the debit orders. Speaking to Minnie Mikayla she informed us that she can request for a reversal but it most probably will be declined. I explained to her about the arrangement made through the team of bankers and still she repeats the same. This is not fair. It's not that we wouldn't have paid but just made the arrangement for later as we can't afford the early run. Can't buy food or electricity as a result.

What is the purpose of contacting the team of bankers when this won't work.
