Ajio — Didn't receive refund of the product ordered in December

I ordered a product in December which never showed up. The delivery got cancelled. It was a prepaid order.
I complained several times. They initiated the refund request on 25th February.
It/s 22nd March now still didn't receive any refund.
This is the Acquirer reference number they provided saying the refund has been initiated :
