Bond repayment debit order account not changed

On 17 September I called the ABSA home loan department to change the bank account from which my bond repayment should be debited. I was emailed a form to complete and send to ***. I completed the form and emailed it on the same day.

I just found out today that the debit order account was never changed and the previous account was debited again this month. This is really, really bad service. Luckily I had sufficient funds in the previous bank account for the debit order to be honoured. I am really not happy with the ABSA home loan department.
