Go Airlines — Cancelling of flight

Address:	18-2-112/5 falaknuma station road ghouse colony
Website:	www.goair.in

I have booked a flight on 22nd of june from delhi to hyderabad from Go airlines.on 27th night i got a message saying flight has been cancelled and without mentioning any reason and messaging this is beyond our control.i have work on 29th of june morning in delhi and have to return back to hyderabad same evening.
They have processed for refund but are explaining it might take 30 days.
I would like to lodge a complaint againt go airlines for being careless towards customers and devaluating me.
They even can accomodate me for same day saying there are no flights whole day.
