Tried to change the return date…
I simply tried to change the date of my return by a day the day after the initial booking. The system was terrible. I ended up doubling the cost of my trip and booking duplicate tickets I then had to try and refund. When I contacted train pal they just failed to understand the problem properly and despite being in touch with them over a couple of days they refused to try and put things right. What an unhelpful expensive mess. Avoid.
