Kotak Mahindra Bank — google play refunded. bank side refund not reflected

I made a transaction of Rs. 529 on 27-Feb-2024. On the same day, the merchant has initiated the refund from our side and says it will be credited 1 to 14 business days or take up to 45 business days. Still not credited in my Kotak rupay credit card ending with 2030. I contacted the merchant today, he says we refunded successfully from our side. Please contact your bank. I'm attaching the refund details shared with my merchant.
