HDFC Bank — refund issue

Address:	Mumbai City, Maharashtra, 400101
Website:	Payzapp

I have paid oyo rooms an amount of 8406 on hdfc payzapp application whose refund was then initiated from their end and even got a confirmation from them about the refund initiation.
I still haven't received any message from payzapp about the same or have any updates.

A similar transaction had happened to my debit card which was successful in a day but the payzapp application has failed to refund this amount. Please solve my issue.
