Indian Railway — late arrival

I had booked a ticket (Pnr no.[protected]/hwh to ghty) through irctc on[protected] in the premium tatkal quota for journey on[protected] in the train no.15959/kamrup exp to reach dimapur by 10pm/[protected] as i already had a confirmed ticket for journey from guwahati to dimapur in the same train. Ticket costs rs.1265 which is approx 3 times of the general fare. But the train arrived dimapur in late (More than three hrs delay) at around 0105hrs on[protected].
I should be reimbursed the pt charges for late arrival of the train.
