Complaints and compliments

We want to know when we've let you down so we can make things right.

Tell us about your complaint

If there’s something we can improve, or you're not satisfied with our products, services, staff, complaint handling process, or how we handle your Consumer Data Right (CDR data), 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 and try to find a solution that's fair and reasonable. At all times, we follow our complaint handling principles.
