Debit order **** by FNB to charge fees

FNB deducted a debit order of 269 from my account and I received a notification of this debit at 3am this morning (06/08/2024). Today at 13:50 I receive a notification that the debit order failed due to lack of funds which is odd as they did initially debit the amount, from my understanding a debit order will not go through at all if there is insufficient funds in the account you will be notified at first attempt but that was not the case her BECAUSE THERE WAS SUFFICIENT FUNDS FOR THE DEBIT ORDER. What is even more suspicious is that the supposed insufficient funds were sent back to my account but not before FNB helped themselves to a nice R105 of my money for “insufficient funds” the funds are sufficient for FNB to ***** but not sufficient to pay my debit order. I will be taking this matter further to the Ombudsman because the ***** and theft on customer accounts by FNB is ridiculous.
