Shameful behaviour by Trainline. … I bought 3 return tickets to Newcastle on 30th September. Trainline informed me the trains would be cancelled due to the strike. I duly cancelled my tickets on the app and sent Trainline ALL the tickets by recorded post, as requested, and I have receipt of delivery. When I questioned why I had not received my refund, Trainline said I had not sent the tickets back. I sent Trainline proof that I had indeed sent them back and they had received them and, lo and behold, I suddenly received part of the refund but not all. I have chased this up and Trainline now say they didn’t receive all the tickets - they can only find some, Luckily, I took a photo before I sent them of my letter and all my tickets as proof. I cancelled all the tickets in the app and I could not have used them anyway because of the strike. Trainline are lying saying I did not send all the tickets. This is absolutely not true! It is clear that my envelope with tickets was mislaid by Trainline in the first place as I had no refund until I chased them with proof of my envelope being delivered and now they are still withholding my money - and it is a significant amount. Shameful behaviour by Trainline! I would avoid using this company at all costs.
