Indigo Airlines — Canceled tickets just before 10 hours of flight

Address:	Chandigarh, Punjab, 400093
Website:	www.goindigo.in

Flight was scheduled for 9th july 2017 at 7.30 am from chandigarh to dibrugarh via delhi.
Part of the flight was cancelled just before 10hrs.
They have informed me so late that being a tourist and a lone female traveller, i had no options of travelling to delhi from chandigarh so late.
When i called them, they have kept my call on hold twice and disconnected.
They have asked me to postpone the tickets by a day but they wont be responsible for my security and the extra expense that i had to bear for an extra day.
I have given so many options but all rejected saying not as per the policy.
I had to shed extra amount of 5k just to travel to delhi and they are not ready to pay the amount difference as well.
