Spice Jet Airlines — Refund for the cancellation ticket

I have booked the ticket (PNR : OEPUHA) on Mon, 17 Feb 2020 to fly from Riyadh to Madurai on MON 06 APR, 2020. But I cancelled the to covid restriction. From that time I choose the refund and until now didn't receive the refund.

I sent many emails and called the customer service to get the refund and until now I did not get the payment.
