hi, I have booked a ticket from vienna to prague via OBB rail network. while booking i mentioned two adults but when individual names were asked i somehow skipped mentioning the two names and automatically name of the credit card payer was taken by the system. I realised the mistake when they were emailed to me (I have not printed them as yet). Can you please guide me as to what options do I have now. its a sparchien ticket so its a discounted one.
