GoAir — Flight cancelled without any information

My flight from Mumbai to port Blair was cancelled on 29/10/20 by Goair without informing me. My PNR was T29LPB. I traveled from Pune to Mumbai to catch the flight. It was bad experience with no there on counter to help. Airlines didn't provided me the cab to come back to Pune. The manager just wanted to refund the money. He was not interested in giving any other solution. The way of talking was not appropriate. He kept me waiting for an hour from the time he got to know my grievance. How can an airline cancel the flight without informing the passenger. Very bad experience with Go air.
Please tell what can be done to compensate the physical and mental agony I went through.
