Passenger has not been travelled due to train was running late more than 3 hours and it was very late in the night so passenger has decided to not to travel. As I have been notified by Indian railways that my TDR request has been CR Repudiated. as per the travel policy, passenger can file tdr and eligible to get the full refund whose train is late more than 3 hours. Please help me to get my refund because this repudiation is against the railway policy.
