I booked the wrong tickets for one day and meant to book them for the following day. This was admittedly my own fault, so I rang customer services in an attempt to change them. His efforts to get my refund and rebook the tickets for the right day were appreciated, however, the lack of decent communication, be it down to the phone lines or just general understanding, meant I ended up assuming I was paying £35 and ended up paying more. I was also extremely confused on when I would get refunded and how much I would be getting back. All very stressful and could have easily been avoided if the workers could have been far more clearer and simpler about what the situation was with my tickets.
