Dear Sir,

But I have not receipt the refund amount since more than 4 months passed. I written so many mail to tdrprocess@irctc.co.in and to care@irctc.co.in. latest reply from tdrprocess@irctc.co.in is as: "Dear Customer, Sorry for the inconvenience.Kindly note that your refund case of PNR No.8617551882 has been forwarded to CCM/ER Railway on 12-Nov-2013 .We have already issued Reminders on 18-Feb-2014 to concerned railway...
