Debit order

<p>Settled my account after getting a settlement figure from FNB. Received a statement that the amount outstanding is zero and no further payments is required. To my surprise they deduct another payment at the end of the month.Now the problem is getting back my money and I do not know who to talk to.The response on emails is that it has been handed over to their legal department. What do they have to do with a debit order that was not stopped after settling the account</p>
