Nedbank changed my debit order date without permission

<p>I have a personal loan with Nedbank and for the past few months they have debitted my account earlier than my contracted debit date. The funds are being debitted from my account before my salary is paid and this could result in funds not being available for the debit - then making me responsible for charges on my account that I had no part in. I want my debit order date to be the date that I contracted with Nedbank, this is the only date that I agreed to and Nedbank cannot unilaterally change my information. I need this sorted out urgently and I do not expect to have to face any consequences such as charges or interest related to this.</p>
