Air India — cancellation of ticket from delhi to bangalore pnr no. j6z5z

Sir i m booked for delhi to bnglr & return as well vide above pnr since i had to reach delhi by train from jammu to catch the flight but due to dera sacha sauda episode all trains from jammu have even cancelled. Kam unable to reach delhi due to this national shame as no bus or taxi is plying on the route since the situation is out of my control. I should not be made to suffer for the fault of the state as such request u to cancel the delhi to bnglr part of the ticket with full refund. Hope u to act reasonably & oblige. Thanks
