Indian Railways
Excessive delay of train

I had purchased a E Ticket for train number 4650 SaryuYamuna exp from Amritsar. It was travelling about 6 hours late from the departure time of 12.00 PM. Due to this I had to travel by bus to reach Delhi on time. I could not cancel my ticket as the reservation clerk said they did not have any info about the delay and they will cancel only after that for a refund. I was travelling throughout the day after that and could not cancel. Now I cant cancel as the chart was prepared.
