Air India — delay in flight ai 679 causing inconvenience in my further travel from mangalore

I had boarded ai 679 from bom to ixe at 0945h on 26 mar 18. I had to further catch trivandrum express from mangalore station at 1420h to reach my unit in payyanur but due to such a long delay in the flight i missed my train and on speaking to officials, nobody seems to be able to do anything or compensate for my financial loss of the train ticket and the inconvenience caused to me.
