Air Asia — Refund against flight tickets

I am being chasing airlines n customer service team from past 3 months.
Nobody is answering calls over customer care number for more than 50 minutes.
If luckily your call get connected then the customer service representative will again hangup your call.

If i am raising tickets through email then getting copy paste response and ticket got resolved.
Again i have to raise a new ticket.

I am being chasing them for 9000 inr from past 3 months and nobody is helping.
