Nedbank debit issues

I have had a Nedbank credit card for a number of years. I have elected to settle my outstanding debt every month, with the amount being debited from my FNB business account.

The debit did not go through successfully at the end of December, and I received an SMS early in January advising that a payment was due. A charge was also levied for the unsuccessful debit attempt. I got in touch with the credit department, and it was discovered that the debit was attempted on my Nedbank Savings account, not the FNB Business one as usual.

I requested an investigation into why the change occurred, as I had not requested it. In the meanwhile, a debit was successfully done on the Business account to settle the payment. I have not received any feedback regarding the change.

I have been watching my account for a debit this month. Nothing has been done thus far. In order to avoid further issues, I contacted the Nedbank call centre on Friday the 3rd of February, then again on the 4th to establish why the debit has not been done yet. I was advised on both occasions that all is in order, and the account is in good standing.

I would like to know if a debit will still be done this month. If not, will a full settlement be expected next month? Will there be any interest or failed debit payments be levied on my account?

I am still waiting for the outcome of the investigation into the original issue. All charges from this time should be reversed. I would also like to get confirmation as to when I can expect my debit every month.
