Wasting my time

In last week I went for a loan with Capitec and that went very well ,thank you for that service. <br> <br> But now I did not give any authorisation for Capitec to go and change my debit orders to my capitec account .My salary does not get paid into my Capitec account but 1life direct received documents to change my banking details.<br> <br> I find this unacceptable if 1life direct did not inform me that my details was changed,my debit would have gone off on the wrong account, I wanted to switch to Capitec but now I am having doubts as how can you go ahead and change my details without my consent.<br>
