Indian Railways — poor service cause financial loss

Sir,
My name is hitesh i am working in a public sector bank posted at kannauj uttar pradesh . My native is in gir somnath district of gujarat.
I have planed my journey from kannauj to native place for attending post funeral rituals of my maternal grand father as I was not got leave at the time of his death. I had booked flight of GO air from Delhi to ahmedabad which was scheduled 1 September 2018 7:25 am (departure time) as to reach delhi i had booked train form Kanpur to delhi on 31 august 2018 whose departure time from Kanpur central station was 16:55 and arrival at new Delhi station was 22:15 . I have booked this train ljn swarna shatabdi(12003) a premium category train of indian railways as to reach delhi 7 hrs before my flight to avoid unexpected delay in delhi.
On the day of journey i have boarded train from Kanpur central on time but after departed from Kanpur train reached etawah station around 18:15, where train was parked for around 7 hrs and no official announcement either of breakdown or status of progress repairing work was held . Train departed around 2:00am from etawah station in 1 sep 2018 morning and reached new Delhi station 7:30am due to which I had missed my flight to ahmedabad and I booked new ticket after reaching airport because it was very important to attend that ritual on that day and as not to miss my onward planed journey from ahmedabad .

Due to careless service and irresponsible behaviour of indian railways i have inccured financial loss and mentally harassed for 7 hrs long sitting at a isolated place with and was not able to attend that rituals due to this long delay by railways
Kindly do the need full and atleast arrange me return of my financial loss wich is 7739rupees(which is nrarly 35 percent of my monthly earning)

Kindly find screenshots of tickets
