I went to London in the week by Train, booked on tinternet with ticket collection at a station, machine not working at Heath High level platform for ticket collection but working for a ticket into Cardiff central, ticket collections not working at Cardiff Central was told to show my email confirmation with my collection number, no one on the Train to London asked for my ticket, they messed up my tickets at Paddington, the 19.15 train was rammed coming back had to stand to Bristol Parkway. whilst the stress of not driving in London was fine, not being able to have a seat for the return journey was piss poor, the staff just didn't seem to know procedure, with different instructions given. Overall it was poor.
