Amazon — Refund not credited back after 1 month

I had ordered few things from amazon and payment was prepaid. But i cancelled the order later and amazon confirmed that they have initiated the refund process on 20/7/2022. But even after one month of constant emails, calls and everything i haven't got my refund back. They said its been completed from their side and check with the bank. Bank has no clue about this refunded amount.
