GoAir — Flight cancelled and customer care not reachable

Address:	Mumbai City, Maharashtra, 400025
Website:	www.goair.in

I had booked a flight from Mumbai to Delhi on 11 July. Got an sms from go air saying the flight is cancelled and reach out to customer care. First of all I don't understand why we have to call customer care if go air cancelled the flight. It should be their responsibility to contact the customer.

Called the customer care number. which was waiting on another call. I don't understand what kind of customer is serves just one call and goes on waiting if someone else calls at the same time.

After many attempts the call went through but no one bothered to pick up.
I am not sure how to proceed now.
