I ordered a product from Amazon of Rs. 1295 then returned it. Amazon told me that Rs. 1295 has been successfully processed in my account on 11 January 2022 and that the amount should reflect in my account by Next 5 business days. I waited for about a week but still not received the money then I contacted Amazon and they told me to contact my bank which is Indian Bank and they also gave me a Refund Reference Number for the transaction which is[protected]. I contacted the bank customer care and they said that they couldn't do anything to help me. Amazon has already initiated refund but I cannot receive it in my bank account . I want my money back.
