Appalling customer service. App would not allow me to book in real time at cost of £11 would only allow prebook at extortionate price of £44 I needed to get to the station so booked.I called customer services who have since acknowledged a technical issue but have refused to help despite me contacting before my journey. I asked them to Change by booking but this was rejected A supervisor said to raise after my journey What a joke! I feel scammed out of £30 plus.
