GoAir — complaint regarding cancellation of flight

I have booked flight from kolkata to hyderabad for 3 feb'20 pnr: eerwfr. But i got one mail that that flight got cancelled after that i tried customer care number multiple time either it was ringing and no one has picked or else it was going busy. On 1 feb'20 i was able to talk to them and ask the agent to reschedule it for next day or in same day but she told that there is no flights available of go air airlines.

I even requested her to schedule a flight with other airlines to that also she told its not possible. I have booked ticket a long back to avoid price hike during last minute. But i had to book another ticket with indigo a day prior to the planned travelling which cost me more than 9000 inr and that too late night for a female passenger which causes a lot of troubles to me and i had to make other necessary adjustment.

I even mailed them 20-22 days ago but did not any response. If airline has cancelled its flight then it should arrange alternate for the the flight. It is there responsibility to take care of their customer they cant escape saying that it has been cancelled. When we cancelled our ticket we get almost nothing as refund but when they are cancelling it they send a mail only. It causes a lot of problems to me and i need compensation.

I have added the tickets details in the photos.
