Ibibo Group / Goibibo — Refund still not credited

Respected sir/mam,
I had booked a train ticket on 20AUG from Bangalore to Pondicherry and payment was done via upi. But for some reason, the ticket was cancelled and a refund was initiated immediately. A mail was received regarding the same and I got the message that the refund will be deposited in my bank account by the time of 27-30 AUG. In the failed booking section it is showing a refund credited in the account but I haven't received the money yet.
Below is the booking details and RRN Number provided by them.
Bangalore Yesvantpur Junction - Puducherry Railway Station
PUDUCHERRY EXP # 11005 • SleeperBooking ID - TRNDGCRN1132W3
₹ 1, 594 has been processed in UPI, refund with RRN number[protected] has been processed to your account.
I humbly request you to help me regarding this.
Best Regards
Utsuk Pandey
