Debit Order Taken without approval

Good day<br> <br> R1000.00 was taken out of my account without my approval. I dailed the *** provided but no answer.<br> They say its for unpaid loans which I do not understand. I think whether any person pays or not, should the bank not inform the client? Should a phone call not be made? Yes I have a loan with FNB, but a debit order goes off every month towards the loan. So whats your excuse? I have seen 4 complaints so far with this exact same issue.<br> Please have this money reversed back into my account. If the installment is too low, contact me to discuss it and find out how it will suit my pocket.
