CommBank support / Compliments and complaints

Give a compliment

It’s great to know you had a positive experience and our team made something easier, quicker or special for you. Saying “thank you” goes a long way and can make someone’s day.

Tell us about your experience so we can make sure the person or team you’re complimenting hears about it, and gets the recognition they deserve.

Make a complaint

If you experience a problem, or you're dissatisfied in any way, it’s important we hear about it. We’ll take your complaint seriously and work with you to address your complaint quickly, in a fair and transparent way.

How it works

  1. Gather documents or records with names, times and dates to explain your complaint
  2. Tell us about your complaint and how you’d like it resolved
  3. We’ll acknowledge your complaint and give you a reference number
  4. We’ll do everything we can to fix the problem and make things right
  5. We’ll address what’s caused your issue so it doesn’t occur again for you or anyone else
  6. We’ll keep you informed of our progress and let you know once we have a resolution

How long will it take?

The fastest way to have the problem resolved is to visit your local branch or call our complaint team. Any of our staff can help you.

Most complaints can be resolved in days. If there is a delay or the issue is more complex we’ll keep in touch regularly.
