[Resolved]  Indigo Airlines — did not get refund for flight cancellation pnr: hfz5nm

I had to cancel my wife's flight ticket on 22nd march, 2019 due to sudden demise of my father on 18th march, 2019. I informed indigo over the call immediately and cancelled the ticket. They have processed me only 1500 rs refund as per t&c and aked me to submit my father's death certificate and they will process the refund for rest of the amount.
Hence i did sent an email to customer. [protected]@goindigo.in twice (On 15th april at 9:03 am, 22nd april 10:50 am) with my father's death certificate. But till now i have not heared anything from indigo and they have not processed the refund amount to me.
I called the indigo customer support team today, but they are not willing to help me with this regard. Hence i am writting here as a hope. This is very very unprofessional & unethical behaviour that i have received from indigo. Which i thought to escalate here so that i get a justice.

Attached you the details of communications with indigo. Here are the details of the ticket:

Pnr: hfz5nm
Traveller name: arpital bose
Travel date: 22nd march, 2019

You can contact me if you need any further clarification.
