If zero stars were an option I would be giving this. I cannot begin to describe how disgusted I am with Trainline's customer service. I was due a refund for two tickets and was told to post them back to Trainline, which I did. Upon only receiving a refund for one of the tickets I got in touch to ask why the other refund hadn't come through. I was told that "only one ticket has been posted back", which is absolutely untrue. I have asked to speak to a manager multiple times, only to be told that there is nothing they can do as "only one ticket has been posted back". I am absolutely furious that Trainline have repeatedly insinuated that I am a liar, when in fact the ticket has been lost at their end. I have asked to make a formal complaint, and my emails have been ignored. I would 100% NOT recommend Trainline.
