Ibibo Group / Goibibo — not providing refund

Address:

Goibibo, Mumbai City, Maharashtra, 400077

I booked a ticket PNR: GQ9BSR.
The ticket had to be cancelled because of corona virus.
I called airlines to reschedule the ticket they cancelled the old ticket as an exception and booked a new ticket.
The new ticket was Rs 5530 cheaper indigo airlies said I need to call goibibo for refund..
When I call goibibo they say no refund request received. But when I enter my old PNR it clearly says that 5530 needs to be refunded.
Request goibibo to pls refund the hard earned money.
