Go Air Airlines - Airline cancelled flight without refund

Go air cancelled my flight and I was not in the country. My flight was from abroad to India. All I got is an email of my flight being cancelled. They haven't replied at all to me post that. Now I am trapped abroad, and I had to book a different airline ticket on my own expense. I have had to pay more than double for the same. GO Air has been a trusted airline for years for me. But I now realize how POOR the service is. The airline is totally quiet about it. In fact, to reduce SEO of refund and cancellation complaints on google, they have played some tactics as well... It is horrible to go through this. it is very much hurtful that I had to bear so much pain due to airline cancelling their flight post which I haven't gotten any support.
