I have a ticket from SBC to TCR in 3 AC by 12677 exp date 10-03-2011. I hav not travelled by that train, when i went for cancellation across the counter after 10 days they said the PNR is flushed and i have to apply through TDR. Whats the best way to get refund as i stay in Secunderabad and this particular train originates from SWR.
