How do you keep track of my complaint?

We log every complaint received at our Customer Services centre on a database with a unique reference number. This enables us to track the status of your complaint and to monitor that we have responded within the timescales set out in our complaints procedure.

How do I know my complaint will be treated fairly?
To ensure that our response is fair and without bias, we will investigate all complaints thoroughly. We’ll reply with a full explanation and, where appropriate, an apology. If you raise more than one issue in your complaint, we will deal with each issue in this way.
I don't feel my complaint has been resolved adequately. What else can I do?

If you’re unhappy with our response please give us the opportunity to try to resolve your complaint. If you’re unhappy with the response you receive, you have the right to appeal to the Rail Ombudsman. The Rail Ombudsman is there to help resolve on going complaints between us and our passengers. It’s free to use their services and they are independent of the rail industry. They don’t take sides, but just look at the evidence available. They will help us both to try to reach an agreement, but if this doesn’t happen, they will make a decision based on the evidence they’ve received. If you agree with their decision, then we have to act on what they say.

You can appeal to the Rail Ombudsman if:

  • you’re unhappy with our final response to your complaint which will be contained in a letter or email (sometimes called a ‘deadlock letter’); or
  • we haven’t resolved your complaint within 40 working days of receiving it; and
  • no more than 12 months have passed since we sent you our final response

There are some complaints that the Rail Ombudsman won’t be able to look into, for example if it’s about the way one of our services has been designed, industry policy, or if your complaint relates to an event which took place before the Rail Ombudsman service was established. If that’s the case, then they’ll contact you to let you know. If possible, they will transfer your complaint to another organisation that may be able to help you further, such as Transport Focus or London TravelWatch – the independent consumer watchdogs for the rail industry. They will independently review your complaint and where appropriate, follow things up on your behalf.
