We’ll send you a final response within 8 weeks. Our aim is to resolve your complaint well before this.

If your complaint is about a payment or a payment service - such as a Direct Debit or account statement - we aim to respond within 15 days. Sometimes we may take up to 35 days to respond. If so, we’ll let you know.

What can I do if I’m still unhappy?

MBNA is a member of the Financial Ombudsman Service, which offers an independent review service. If you're still not happy, you can ask the Financial Ombudsman Service to look at your case. This service is free.
