We aim to resolve your complaint as quickly as possible

To help us to do this, please tell us:

  • Your name and address.
  • Your preferred contact number.
  • Your 16-digit card number and any useful references.
  • What’s gone wrong and when/how it happened.
  • What you’d like us to do to resolve your complaint.


How we’ll handle your complaint

We aim to resolve complaints straight away, but some can take a little longer.

If we’re able to resolve your complaint quickly, we’ll send you confirmation that your complaint has been resolved. But if we need to look into things in more detail, we'll send you a prompt acknowledgement.

We’ll work to resolve any complaint received within 56 days and will keep you updated of our progress. When we’ve thoroughly investigated your complaint we’ll send you a final response.

If your complaint isn’t resolved

If we’re unable to resolve your complaint within 56 days, or you’re not satisfied with our final response, you can refer your complaint to the Financial Ombudsman Service and ask them to review the situation.
