Booked 3 journey's with Rail Ninja and two of those were not honoured. Luckily one was when I was still in the UK and I rebooked on a train at a slightly different time. I booked business class for all three bookings and they offered a lower class and refund on the same or different trains. The second change, I had just arrived in China realising you couldn't use Google and was panicking especially when you're travelling with your 80 year old mother. Luckily the concierge at the hotel made the booking for me and I cancelled the Ninja Rail booking, although the booking did cost me a surcharge from the hotel. Why did you not offer an alternative train, similar time and journey time where the business class booking was honoured?
