Tell us about your complaint

We're listening

If you have a complaint contact us in the first instance. If we've done wrong, or you're not satisfied in any way, it's important we hear about it so we can make things right.

We'll take your complaint seriously, work with you to address your complaint quickly and aim to find a resolution that's fair. Sometimes we may need more time, but we'll keep you updated regularly throughout the process to let you know where things are at. 

How it works

  1. Gather any supporting documents or records with names, times and dates that will assist our investigation into your complaint
  2. Get in touch to let us know about your complaint and how you’d like it resolved. The quickest way is to call our complaints team or visit your local branch
  3. We'll acknowledge your complaint, give you a reference number and the name and contact details of the person who is handling your complaint
  4. We’ll do what we can to fix your problem, making sure it doesn't occur again for you or anyone else and let you know once we have a resolution

How long will it take?

Most complaints can be resolved on the spot or within days. We'll keep you informed of our progress and if we're unable to resolve your complaint within 21 days we'll tell you that we need more time to investigate.

In the event of a delay and we're unable to provide you with a final response within 45 days, we'll tell you the reason for the delay, give you a date you can expect to hear an outcome and update you monthly.

If you're unhappy with the resolution

You can contact our Customer Advocate or lodge a dispute through the Australian Financial Complaints Authority (AFCA), our external dispute resolution provider. AFCA provides fair and independent financial services complaint resolution that is free to consumers.
