I HAD BOOKED THE AC-II TIER TICKETS FROM FAIZABAD TO DELHI IN TRAIN NO.4205 FOR MYSELF AND MY WIFE AND DAUGHTER UNDER PNR NO.2539775158 FOR TRAVELLING UPTO DELHI, THE TICKETS WERE RESERVED UPTO DELHI BUT WHEN I REACHED THE ORIGINATING STATION, TO MY UTTER SURPRISE THERE WAS NO AC-2 COMPARTMENT IN THE AFORESAID TRAIN ON ENQUIRY I WAS ADVISED TO TRAVEL IN AC-3 TIER UPTO LUCKNOW AND WAS TOLD THAT AC-2 TIER COMPARTMENT WILL BE ATTACHED IN THE TRAIN FROM LUCKNOW ONLY. THE TT IN AC-III TIER HAD REFUSED TO GIVE THE CERTIFICATE OF TRAVELLING IN AC III TIER (LOWER CLASS) THAN THE BOOKED CLASS. I WANT THE REFUND OF DIFFERENCE OF FARE FROM FAIZABAD TO LUCKNOW THAT IS THE DIFFERENCE TO AC-II AND AC-III FARE. PLEASE LOOK INTO MY GRIEVANCE AND REFUND THE AMOUNT AT AN EARLY DATE
