I've had an eTicket for 12625 departing TVC at 11:15 am in 3A for 3 senior citizens. Due to some reasons, I've just cancelled their tickets at 5:15 am, ie 6 hours before departure. Found that the chart was already prepared. So I was asked at IRCTC site to enter a TDR by selecting a TDR reason, which I did selecting the reason "Reason For TDR: Party Could Not Cancel Because Chart Prepared At Originating Or Previous Remote Location". The total fare paid was 2748/- + 20/- service charges. How much refund should I expect and in how much time... can someone please advice on this.
