With the RBA change - we no longer offer AMEX due to the cost, we should be able to disable this. Debit Success are not able to do this currently it is either switch it all off or on which is not a suitable answer. As a result, we need to keep asking Debit Success for a report to check if any parents have changed to AMEX card and have the parent change if required. We have made a note on enrolment form that we don't accept AMEX but it does not stop them entering an AMEX card.
