Debit order dishonored

I had a debit order go off my account on Sunday. I didn't have sufficient funds at the time.<br> I took a temp loan from FNB so that the debit order could go through because normally they will allow you to put money into your account if it is on the same day so that the debit order can be honored. <br> The debit order wasn't showing on my statement yesterday. I got the loan yesterday so today, when the debit order was reflecting on my account and I had sufficient funds in the account they still go and dishonor the debit order to get extra money out of me. <br> I feel that I had enough money in my account when the debit order ran so the order should have been honored. <br>
