As my plan to travel to London had cancelled , I asked for refund. I was told that as it was an advance ticket , I could not refund. This was not mentioned when I was purchasing. I was given an option to re-book for another date , but that could be only be done on-line and cannot be on phone. When I tried it on-line, I could not see and book the return fair at the same time as was booking for on-ward journey. I was given only option to book and purchase for on-ward journey , before I could see fairs for the return journey. To me it is not a fair system. Once a passenger buys an on-ward journey ticket , the return fairs started appearing very expensive leaving the customer no choice , but to buy them.
