The matter was reported to IRCTC, vide e-mail Dtd.11.06.08and requested to arrange refund against waitlisted ticket.
IRCTC replied on12.06.08 that"We are forwading your case to railways for TDR process. Railways check all the matters and decide what amountshould be refunded and this all process takes 90 days or more."
Subsequently various reminders sent on e-mail address"etickets/[protected]@irctc.com", but no satisfactory reply could be received. Even no e-mail is now being replied by IRCTC sent to rermind them that the period of 90 days has lapsed long back. The last mail sent on 06.11.08 is also unreplied.
