GoAir — flight got cancelled

I received message saying my goair flight from hyderabad to kochi on 31st january got cancelled and if i wish to avail for a flight on same or next day at no extra charge, they requested to call them on [protected].

I called this number so many times, they haven't responded for any calls. I waited for long time on the call for them to respond. Very pathetic, they don't have any concern for the customers.
