Indigo Airlines — flight cancelled by indigo but refund not processed

Address:

Level 1, Tower C, Global Business Park, Mehrauli-Gurgaon Road, Gurgaon – 122 002, Haryana, India

My pnr was fdhvrl and i have booked my ticket to travel on 27 march 2020, but it got cancelled and i applied for refund on 31 mar 2020.
I already have contact the customer support twice for refund (On 31 march and 4 may 2020), but still i didn't get any refund.

Every time i contact their customer support they are making fool of me and saying they will process the refund with in a week.

One more thing they are deducting 500 convenience fee for no reason.

I have never seen such a worst customer service like indigo where i am not getting any resolution from last 2 months.

I am attaching some snips.

I have booked another ticket through flipkart and i got the refund with out any hassle.
