Banking details not updated, very upset!

Hi<br> <br> I amended my banking details on the 19/10 for the monthly Loan premium to be debited from my Nedbank account. I was assured that the details were updated for future deduction. The first deduction from my updated bank detail would of been as from the 25/11. To my surprise the debit ran on my previous banking details with another institution. I verified this by checking my previous banking details early this morning, i immediately transferred funds into that account and the debit went off immediately. i then received an SMS from Nedbank stating my payment was not received and urgent action should be taken. This has caused me a great inconvenience and is set to blacken my clean credit score. i called Nedbank and wanted answers. The consultant i dealt with confirmed that i called the 19/10 to amend my details but no action was taken by that agent. she then escalated the matter and updated my details again.<br> I would like the late payer removed from my bureau details as this was the fault of the agent that did not update my details. I updated my details with ample time and very disappointed with the inconvenience this has caused me. I am still awaiting a follow up call.
