I was buying a train ticket back home on the Trainline app, and the app by default chose the "same day return" option. I didn't realise that and I bought a return ticket accidentally.Once I noticed it, I called their customer service for a refund, so I can purchase a new single ticket. Maria (the customer agent) on the phone told me only way she could refund the ticket is if I get a new ticket. Then she found a "single one-way" train ticket to home for me which also worked for my schedule. She told me to buy that, so she could refund the money for that accidental return ticket. I did buy it as this was the ticket I was intending to buy from the start anwway, and she promised that this was the only way she'd refund the ticket. It has been 2 MONTHS and 2 weeks and I still haven't received a refund. And I have emailed trainline, 13 TIMES over this period, and they always said they are working on it, then they completely stopped replying.. I'm currently trying to get my money back from Trainline with the help of my bank!
