Railway booking is done through irctc. But i donot get any mail on my registered mail id "[protected]@yahoo.in". So how can i know about my bookings. Niether i get the mail regarding my booking of flights. Now i have to cancel some of my booked tickets, but when i have no details how i will cancel them. So pls arrange to send all my bookings either rail or flight to my above mail id and also let me know how to cancel them.
