The customer service and acceptance of errors made on their part is terrible. I purchased a ticket from Wiltshire to London providing the exact times and trains I wished to use. Trainline provided me with super off peak tickets even though both my journeys were peak travel. I then had to re-purchase another partial return ticket to allow for travel and split save. When I drew their attention to this and asked for a refund on the second ticket they employed delay tactics in asking me the same questions several different ways every 24 hours for over a week. They then blamed me for THEIR error and asked for physical proof of the replacement ticket purchased even though they could see it in my account and they are aware that the destination station barrier retains the ticket on arrival.
