FNB refusing to reverse erroneous debit order by service provider

In the past FNB has been very good at allowing clients to dispute unfair or erroneous or *****ulent debit orders. I had a debit order due on the 1st of the month go through on the 23rd of February 2024, a whole 7 days too early. Not a big problem because errors happen. The problem is that FNB is refusing to allow me to reverse the debit order yet the acknowledge that the debit went too early. I spoke to Kabelo in debit order reversals and he said I can not reverse this debit order because it is blocked by the same service provider who got it wrong. So these service providers have special privileges to stop us from correcting their errors even if we have documented proof that the debit order is erroneous. This is just so wrong.....my service provider confirmed that they made an error I have evidence of that too. But they will take 8 days to fix it, I do not have that long. I need the reversal now. But FNB won't allow it.
