They will grab your money at every opportunity. One second after purchasing my ticket, I realised I had accidentally booked for the wrong date. They used to have a cooling off period and be understanding of a simple error. But this time I was forced to pay a £10 admin charge. As a loyal customer, I find this absolutely disgusting, especially when we are already paying ridiculously high prices. They don’t offer any flexibility. In these uncertain times, hotels, flights, you name it have all been completely understanding and offered full refunds. Not Trainline! They will take every last penny they can from you and pocket it. If you can avoid using them, I’d seriously advise that you do!
