I have booked one E-Tickets by online website i.e. www.irctc.co.in but the ticket was not confirmed till 7 PM and Train Timing was 12:10AM on the same night but not travelled and missed the train but very next day i saw the ticket was confirmed and i immediately booked another ticket on the same name in other Train but when i filed the TDR Refund than after six month i got reply via mail from Railway that your refund has been regreted by Railway and i am trying no. but they are not answering

And i am not understanding what to do?

Can anyone let me know
