On July 30, 2025 I made a number of bookings relating to my travel arrangements in September of this year. I made a total of seven bookings, including flights, train and accommodation. Two were on Trainline. I only gave a cursory glance at the acknowledgements, but when I looked at my calender weeks later I saw one of my train bookings was out by a week. I tried to find out why the booking date was changed, because I am sure it was not the date that I booked for my journey. The app has a flow chart style issue resolver, but it just returns the message that the ticket is non-refundable and cannot be changed. I chose Trailine to make the booking because it is an English language company and I believed it would be easier in the event that I needed support for any issues. I tried several avenues to contact someone about the issue, but to no avail. I used an intermediary, PissedConsumer, to make contact with Trainline. They replied saying their system does not make those errors. I know I did not make the error. Their obstacles to communication and intransigence to accept that their system is at fault is infuriating. Trainline is fine until a situation like this crops up. My advice is to look at alternatives.
