Debit Order disaster

<p>I was very proud to almost settle my bond. Since the debit order always adjusted to a lower amount if I deposited more into the account than necessary, I asumed it would happen again. What a disappointment that you debited the full outstanding amount + interest as full and final debit order. Why! If I wanted to settle the bond, I would have paid in the full amount. A previous time, I paid the full amount and lost access to my flexi facility, so I was not going to make the same mistake, but you did it on my behalf. I did not have sufficient funds in my account. Now you expect me to pay in the difference to avoid an unpaid debit order Why?. I phoned your call centre and spoke to Thumi. She couldn't even understand what I was trying to explain. I am deeply disappointed in FNB.</p>
