Airports Authority of India — GoAir flight cancellation

PNR- MY2ITG, flight from Delhi to Indore @ 19 pm, passengers were myself & my wife.

This flght was cancelled by GoAir and it has caused me business lose. I had to book another flight ticket of almost double the price as well. GoAir cancelled ticket was insured with travel insurance and i want to claim the compensation amount from insurance company.

I have chased GoAir multiple times to get the written clarification of flight cancellation. This is 'must to have' details in claim process. But GoAir has not responded to my emails ever.
Its been 3 months now this is pending.
