HappyEasyGo — Refund Request

It’s about more than 65 days, I haven’t received my refund yet and I have sent so many mails to HappyEasyGo customer care about the refund. But instead of my refund I am getting only apologies mails.
I have cancelled the flights because of the rescheduling happened by airline. In such cases as per HappyEasyGo policies all amount should be refunded except convenience fee.
I have paid Rs. 8617 for two flights and after following up with customer care around more than 35 days i got a refund of Rs. 3264 only. Don’t know when will the Management will refund rest of the amount.
Kindly take action on this.
