Raising a Formal Complaint

When you feel that the service provided has fallen short of your expectations, you have the right to raise a formal complaint. Metro Bank aims to address issues at the first point of contact, but if the matter requires more attention, there is a dedicated team to review your concerns thoroughly.

Taking a structured approach helps the bank investigate the situation accurately and provides you with a clear timeline for a resolution. Whether your issue relates to a transaction dispute, a technical failure, or a customer service experience, documenting the details clearly makes the process smoother for everyone involved.

Step-by-Step Resolution Guide

First, speak directly to a colleague at your local store or contact the customer service team via the main telephone number. Many issues can be resolved during this first conversation. Explain the situation clearly and have any relevant dates or transaction IDs ready.

If you remain dissatisfied after speaking with a staff member, ask to escalate the matter to the complaints team. They will conduct a formal investigation into your case. Ensure you receive a reference number for your complaint, as you will need this for any future follow-ups.

The bank will aim to provide a final response letter within eight weeks. If you are unhappy with the outcome of this investigation or if the eight-week period passes without a resolution, you can refer your complaint to the Financial Ombudsman Service. They act as an independent adjudicator between you and the bank.

Troubleshooting Common Issues

MFA or Login Issues

Cause: You may be unable to log in to your secure message centre to submit a complaint because your One-Time Passcode (OTP) is failing to arrive due to a weak mobile signal.

Fix: Switch to a stable Wi-Fi connection or use biometric login (Face ID or fingerprint) to bypass the SMS verification requirement.

Fallback Action: Bypass digital channels and contact the bank’s main customer helpline directly to log the complaint verbally.

Browser or App Errors

Cause: The online complaint form may crash or fail to submit due to stored temporary data in your browser cache or an outdated version of the mobile app.

Fix: Clear your browser's cache and cookies, or update your app through the respective app store before attempting to submit the form again.

Fallback Action: Compose your complaint in an email or a printed letter and send it via the official email address or postal service.

Locked Account or Access Issues

Cause: Your digital access may be locked due to repeated incorrect login attempts, preventing you from checking account details needed to support your complaint.

Fix: Use the "Forgotten login details" link on the login screen to safely reset your access and regain entry to your digital statements.

Fallback Action: Visit a local branch in person. Staff can verify your identity with a photo ID and help you access the records you need for your complaint.

Pro-Tip: Before you submit a formal complaint, compile a timeline of events including dates, names of staff you spoke to, and specific transaction amounts. Providing this structured evidence helps the complaints team investigate your case much faster than if they have to piece together fragmented information.

Frequently Asked Questions

How long does the bank have to respond to my complaint?

Metro Bank aims to resolve simpler issues within three working days. For more complex problems that require a deep-dive investigation, the system allows for a longer review period. Under regulatory guidelines set by the Financial Conduct Authority, the bank has a maximum of eight weeks to send you a final response letter. If you do not hear back within this timeframe, or if you receive a response you disagree with, you should contact the Financial Ombudsman Service immediately.

Can I complain if I have a joint account?

Typically, any account holder can raise a complaint regarding a joint account. The bank’s systems allow either party to discuss issues related to shared finances. A limitation arises if the complaint involves highly sensitive personal data about the other account holder; in such cases, the bank may require both parties to be present or provide explicit authorization to proceed. To avoid delays, confirm that your co-account holder is aware of the complaint and is happy for you to lead the discussion if you are speaking to the bank alone.

What happens if I am unhappy with the bank's final response?

If the final response letter does not resolve the issue to your satisfaction, the bank’s internal process has effectively reached its limit. At this point, the system automatically entitles you to take the matter to an independent third party. The bank will include information on how to contact the Financial Ombudsman Service in their final letter. Keep a copy of this correspondence, as the Ombudsman will need to see it to prove you have already attempted to resolve the issue with the bank directly before they step in.
