Why do I have a duplicate transaction?

Merchants may request authorisation for a transaction more than once and you may temporarily see all of the authorisation attempts on your account. However, you will only be charged for the transaction once.

If you believe you have been charged more than once, we suggest waiting for your next statement to verify you have been charged more than once. Your statement will only show completed transactions.

If your statement reflects the duplicate transaction or if the additional authorisation attempts are still showing on your transaction list after 10 days, you can raise a dispute by completing a Notice of Disputed Transaction and sending it to [email protected]

^Up to 110 days interest free on humm90 Mastercard purchases (excluding cash advances) when you meet the Interest Free Criteria. You must pay at least the ‘Alternative amount to avoid interest’ on each monthly statement, by the statement due date. Any outstanding balance after the Interest Free Period reverts to the humm90 Purchase Rate.
