GoAir — customer care not available

My name is Ashwani Kumar Singh. My flight G8-894/554 scheduled to depart at 12:30 hrs 29 Dec 2019[ Bengaluru (BLR) to Ahmedabad (AMD) ] was cancelled.

I have an option avail a flight on the same day, previous day or next day. I have trying to call customer care for last 2-3 hours and they are not responding.

This is just unacceptable. Now they will tell me that since didn't contact them, I'm entitled to any compensation or refund.

Please help
