How rude can your agent be even when the mistake was on their side

<p>I'm really ****ed by the call I just received now from an agent by the Name of Lerato who called on Behalf of Nedbank Personal Loan around 14:30 today.</p> <p>First week of Dec I received an SMS that Nedbank will debit on the 11th Of December, which I called them and advise that they can only debit on the 21st of December 2015 and received a reference number for the call: *** and was promised that the debit order will go through which it never did. I then phoned again in January and advised them&nbsp;that the debit order did not go through as arranged which I asked them to debit my account twice&nbsp;in March&nbsp;to cover the&nbsp;mistake that was&nbsp;made&nbsp;in December which I &nbsp;received this reference number for the call:***.</p> <p>&nbsp;The same people after our arrangement for march decided not to debit my account in February, thats why now February is also outstanding and dont appreciate they way I'm being treated at Nedbank.</p> <p>How is it my problem that they didnt debit and why should I be insulted the way this Lerato Lady insulted me.How many time should I call and ask them to fix their mistakes? I need her to show me where my debit order was rejected in regards to no funds in Dec and February and also who authourised them to debit my account twice also in April as I only authorised it in march. I'm not going to stand and be insulted because of your mistakes yeeeeeeeer ,she is so dis-respectful and doesnt even check records as I kept on calling and calling for them to debit my account. I'm not going to keep on double paying Nedbank because of their ****** mistake finish and Klaar.</p> <p>&nbsp;</p> <p>&nbsp;</p>
