Indigo Airlines — Flight cancellation

Address: Gurgaon, Haryana

Website: www.goindigo.in

I had a flight from pune to ahmedabad at 11:45pm from flight no 6e673 on 2 dec 2016. They messaged me at around 3 in the afternoon that the flight has been cancelled without any reason and the number which they stated in the sms i. E., [protected] is not reachable at all. I have no means of communication to the airline. Due to this i will not be able to board the flight back from ahmedabad to pune from spicejet. They are charging me a cancellation fees for the wrong doings of indigo
I want an answer for this and i need my money back for all the losses that have been incurred.
