Bank Payment Error - Partial Refund

I routinely complete payments to suppliers by uploading the ABA file. For the first time, there was a banking error with one supplier and these funds were returned immediately. I am aware that it was a bank issue, as I contacted both the supplier and the bank. The supplier did not change banking details, and the bank advised me there were no issues from my end. I contacted the supplier and they confirmed there were issues with their bank. Coincidently, we both use CBA.

How do I account for this as:

1. The funds will now sit separately in the BankFeed
2. There is no refund from the supplier because it is a banking error
3. The supplier will still need to be paid, even though MYOB will have it recorded as being paid.

Thanks for the advice.
