GoAir — refund and customer care not responding about it

I had a flight on 16th March and it got cancelled few hours before departure. I got an email saying full refund will be given, just call the customer service. Now this is my 6th day that I am calling the customer service and no one has responded to my calls yet. I had called their Abu Dhabi office, even they couldn't help me and directed me to call the Indian customer care. I had sent an email on 15th night after I received the message that my flight has been cancelled and until now I haven't received any reply from them. Pathetic Customer Care people. Atleast respond to the emails if not calls.
