How soon should you lodge a dispute?

You'll need to lodge your dispute within the following time frames:

  • Visa debit card disputes - As soon as possible.
  • Credit card disputes - As soon as possible.
  • Deposit and transaction accounts – As soon as you’re aware of an issue in your banking, let us know as soon as possible. Any delays can impact our ability to help you out (you have up to seven years from the date of transaction to dispute it).

Before you dispute a transaction

Before you lodge a transaction dispute with us, please make sure the transaction has been processed by the merchant.

It takes 3 business days for a transaction to clear. We can only investigate a transaction once it’s been processed.

Here are a few things to do before you contact us to dispute a transaction.

Check with your secondary cardholder

If you have an additional cardholder, check if they recognise the transaction.

Talk to the individual or organisation the money went to

Organisations like Apple, Google, PayPal and many others have their own payment dispute processes. Contacting the individual or organisation the money went to is usually the fastest way to resolve a transaction dispute.

Make sure there really is a transaction to dispute

Have you visited a hotel recently? When you visit a hotel or put a security deposit on a purchase, the amount can affect your account balance even though you haven’t made an actual payment.

This is called a purchase authorisation. The hotel or retailer you gave the security deposit to can hold your deposit for up to 10 days.

When you check out of the hotel or complete the purchase, the hotel or retailer should release the security deposit funds back into your account.

The credit card dispute process

Keep making payments!

While your credit card transaction is in dispute you need to keeping paying at least the minimum amount on your credit card statements.

If you usually pay the closing balance on your credit card statement each month, continue to pay this to avoid interest. The closing balance will include the disputed amount. Interest does not accrue on the disputed amounts from the date the dispute is lodged while it's being investigated (including the international transaction fees if it applies).

Provide more information if needed

If we ask you for more information or documents or to sign a letter or some forms in connection with the dispute, please help us out as soon as you can.

We'll respond to you

We’ll send you a letter to confirm the details of the transaction you’re disputing. Please check the details, sign the letter and send it back to us within five working days.

We may also ask you for more information or documents to support your dispute, for example the eBay description of an item that’s different from the one you received or transaction receipts from the merchant.

We'll contact the merchant’s bank

Once we have all the details of your dispute, we’ll ask the merchant’s bank for a copy of any receipt for your disputed transaction.

When the merchant has a receipt.

If the merchant’s bank sends us a receipt for the disputed transaction, we’ll send you a copy. We need you to check the details on the receipt:

  • Signature
  • Merchant name – remember that the shop name, where you bought the goods, can differ from the business trading name on your account statement
  • Delivery address
  • Billing address
  • Product information

If you still don’t recognise the transaction and want to continue the dispute please fill out and return the form we have enclosed with the receipt.

If we don’t receive the completed form, or hear from you, within 14 days of the date we sent you the receipt and the form, we’ll assume you don’t want to continue with the dispute because you have accepted the transaction. We’ll also close the dispute in our system.

If we don't receive a receipt.

If we need to investigate further because we don’t have all the necessary information, we’ll write to you to let you know. We’ll try to respond to your transaction dispute request within 45 days.

We’ll let you know the outcome

We’ll advise you of the outcome of the investigation in writing no longer than 45 days after receipt of your dispute, including the amount to be reimbursed and or charged (where applicable), and the reason for the decision.

Notes on your credit card statement

This explains some of the notes you may see on your statement when you’ve disputed a transaction. But, these notes may not appear where the disputed transaction is an EFT transaction, or is being reviewed by our Fraud Operations Department.

Dispute item raised

This means we are reviewing the transaction and will appear until the dispute process is completed. While this message appears next to the transaction, you won’t be charged interest on that amount.

Dispute resolution credit

This means we have refunded the transaction and will appear next to the disputed amount. The credit on your account will remain unless the merchant can prove the transaction was valid.

Dispute item resolved

This means we have finished reviewing the transaction and the reversal has been completed for the disputed amount. But behind the scenes we keep working with the merchant confirming the transaction. If the merchant is able to prove the transaction is valid, we may re-debit your account.
