Sir i have booked 6 e tickets on 1 oct from patna to jasidih in patna asansol spl train. Train time is 3 :10 but train is late four hrs. And we didn't travelled. I have file tdr and got reason null. Bahut dukh ki bat h ki tdr file reject kyon kiya gaya aur reason me null likha gaya. Agar railway ki galti h to money refund kiya jaye. Plz sir mera amount refund kiya jaye. Sir plz...
