Amazon India Refund Not Processed After Return Pickup

I am using the Amazon mobile app in India and I am facing a refund problem related to my order numbered 407-2447376-5821965. The product was picked up successfully as part of a return, and I received a message stating that the pickup for this order was completed and that I would be notified once the refund was initiated. However, although three days have passed since the pickup, the refund has still not been processed. I am waiting for a refund of approximately 1,500 INR for this order. I cannot see any clear information in the app about the refund being initiated, and this delay is causing me concern. I request that my refund for this order be processed in full without any further delay and that I be informed clearly through the app or email once the refund has been initiated and completed.
