FNB Playing Dirty

I have noted a trend to decline debit order, last night, 12 August 2020 I transferred money to my account for a debit order that they had declined a night before yet have funds in all my accounts. They deducted R240,00 from my account for unpaid debits. I requested Momentum to debit once again, at 22:30 I transferred funds only to find that the debit had happened, and paid it and it showed that it was cleared. When I wake up I find that unpaid debit. The system shows that I transferred fund on 13 August 2020 at 3:00, when I was fast asleep and now seating with a debit of -R2 297.00, which is unexplained. In less than 48 hours they have deducted over R360.00 for unpaid debit. Not in this economy. I will show that I have been fast asleep at 3:00 to have made a transfer
