Sir i had booked 2 tickes for 28 january 2019 train number was 18517 from raipur to titlagarh. Pnr number of the tickets were [protected] and [protected]. One ticket is of 3tier ac and other one is of sleeper. On that day the train was late for more than 8 hrs.
I first try to file tdr on irctc.in but due to irctc site not working i couldnot able to file tdr. But at the same time i had file tdr through 2 mails on 29 january 2019 at 1.30 am and other at 1.31 am on 29 january but they have taken only the tdr file request of sleeper tickets only and other was repudiate. I am enclosing the screenshot of that mail where the time is mentioned of tdr file and that was in time limit when i can file the tdr. But railway authoity says that it was not timely filed and repudiate the tdr
