Spice Jet Airlines — lack of refund

I had booked flights from mumbai to kochi for today 02/01/18 16:30 pnr n5vzwv for my wife roopa alex and two kids. On the way to the airport rioting started and they had to take another route. Even along this only alternate route rioting started and the roads were blocked on the way from new bombay to the airport - only 20mts away from the airport - with police not allowing further travel. I called spicejet and asked to cancel the ticket. I was told that it is less than 2 hours for the flight to go and that they had received no notification about the riots: i told the customer service person that it is also on the news but he refused to listen. I asked to speak to his manager and kept me on hold and i never did get to speak to the manager. I am now booking the same spicejet flight for 3/1/18 16:30. I need to be refunded for my original flight after cancellation fees.
