What can I do if I have any concerns or feedback?

You can give us feedback or escalate an unresolved concern through the Compliments & Complaints form.

Feedback will be lodged and passed on to our humm90 Platinum Mastercard team for consideration. You will not receive any further correspondence from us.

If you’ve lodged a complaint or unresolved concern, we will contact you within 10 business days.

If you are unhappy about the resolution of your concern, the Australian Financial Complaints Authority (AFCA) helps individuals resolve disputes with financial service providers. You can reach them at and by calling 1800 931 678.

^Up to 110 days Interest Free on humm90 Mastercard purchases (excluding cash advances) when you meet the Interest Free Criteria. Failure to make the required payments will result in you no longer meeting the Interest Free Criteria meaning that all new transactions from that day will be interest bearing from the date of the transaction. Any outstanding balance after the Interest Free Period reverts to the humm90 Purchase Rate, currently 25.80% p.a. and subject to change. Minimum monthly repayment required.
