I have a problem. I recently booked a ticket to London through East Coast trains. I selected the print@home option and they asked for a ID proof. Being an international traveller I naturally gave my passport number. Unfortunately I forgot to change the options and the ticket recorded the "preferred ID proof" as a driving licence with the last 4 digits of my passport. Now I am really worried since tickets on this route are quite expensive, and that the ticket checker should not create any issues while travelling.
Could someone suggest what to do? I tried to email the train company from their website, but so far no one has responded!
