Aircosta — refund amount not paid for cancelled flight

Hi,

I have booked aircosta flight lb 693 from hyderabad to tirupathi for 12th march 2017. On 7th march we cancelled the ticket as we received information that all aircosta flights were cancelled. Requesting a refund past six months. Booking agent (Mmt) says that they are not yet got any amount from airlines and couldn't process my refund.

Regards,
Venkat
