People who have paid extra to reserve a specific seat on a train and then been made to sit somewhere different.

Under consumer law, companies cannot get away with charging you for something they then don't deliver.

Make a formal complaint to the train company and demand a full refund of your seat reservation fee.

Say the fee you paid for that particular seat was a separate charge on top of the ticket price.

Add that you were not just requesting a seat in the same way anyone travelling on a train can do when they check in.

If you've booked a particular seat and cannot sit there, complain to the company.

Say that under section 41 of National Rail's Rights of Carriage you are owed a partial refund as your seat reservation wasn't honoured.

There's no rule setting out how much you will get back as private rail firms can decide this for themselves.

You'll need proof of your ticket reservation. If you can, take a picture of the seat number you ended up sitting in on your phone.
