Air India — delay / late information of delayed flight

Departure of KOL –HYD flight was 19.00 on 06.01.2019 . Flight no AI0526, PNR: JFVP0, Ticket no[protected]C1. My residence is 60 km from Dumdum airport. Call to intimate me regarding the delayed departure was received in my mobile at 5.01pm when I was entering the airport. The flight departed nearly about 10.00pm and reached HYD after 12.00 i.e on next day 07.01.2019. What is the use of purchasing flight tickets in evening when night flights are available at cheaper rates. Why the intimation was served so late when you are suppose to report 2 hours before departure of the flight. Who is responsible for my harassment and upsetting my programme . I want a token fine of Rs. 1000.00 for my harassment.
