Hi I've previously clicked on proceed booking... but nothing pops up for payment?

Also the departure and arrival date are a little messed up :( It is suppose to be an overnight train but it says there that the arrival and departure dates are the same. i'm a little confused and I clicked many times. How do I cancel them all?

Sorry for the inconvenience caused.

Thank you
