Indian Railways — excessive delay of trains

Address:

Pnr no: [protected]
Train no. & name: 02821/pune src sf spl
Class: second ac (2a)
Date of boarding: 01-jan-2018
Scheduled arrival: 02-jan-2018 14:15
Total fare (All inclusive): 6040.00

This seems to be a special train with superfast charges applicable. My parents boarded this train on 1 jan 2018 after a delay of 7 hours and as of now the train is running at a delay of 11 hours. If this be the case, why call such trains superfast and railways should refund 50% of the total fare charged on account of inconvenience caused to passengers to their inefficiencies.
