Indian Railways — About Refund of the train ticket which was cancelled.

Address:

Mumbai City, Maharashtra

I booked my ticket from kanpur to Mumbai having PNR number [protected] and transaction ID [protected]. This train (Pushpak Express was cancelled). I was hoping that the amount will be refunded back. But till now no processing has been done on refund. I contacted customer care and they are telling that I should have cancelled ticket for refund purpose. As the train was cancelled so it becomes there responsibility to refund money for those who did online transactions. Now they are telling nothing can be done. This is not tolerable. Its a hard earned money. Help for this.
