Then I was filled TDR on same day on same time but still I have not received any response from your side as well as still not received my refund amount in my account.
PNR detail is :-PNR:[protected], TRN:15111, DOJ:12-02-19, CC, DLR-BCY, DP:07:03,
SWETA SINGH, C1 35,
Fare:260+AGENT CHGS, IF ANY.

Above all facts I have already shared many times to Irctc directly but every time they are only says that I have not filled TDR before 04 hours of scheduled departure.
How can I filled TDR before 04 hours of scheduled departure in above detailed situation .

So, request to you please look into this matter and do the needful at the earliest.
