Unauthorized debit order

<p> </p> <p>An unauthorized debit order has occurred in my standard bank account from NAEDO MZANSI4U and I would like to be helped to stop the debit order since I don't know these people and have no agreement with them and will never ever have personal agreements with any company telephonically. I have communicated with the bank and it seems as if they have no idea on how to stop these debit orders for good so I seek help to stop the debit order for good.</p>
