HDFC Bank — complaint regarding unreceived refund on my hdfc bank debit card

I am writing to inquire about a refund that I have not yet received in my HDFC bank account ending in 1192.

On March 31st, 2024, I received a notification from Amazon India stating that a refund of ₹45, 070 had been initiated for an item I returned on the same date. The refund was processed from Amazon India's end.

However, after waiting for 5 business days, the refund has not yet been credited to my HDFC account.
