Flipkart — Note received refund money after product pickup is done and returned is cancelled

I have ordered Asian shoes on the product was delivered on 31 aug 2023 I had issues with the product therefore I applied for return. The product was picked On 5th September 2023 but on 6th September there are showing your return is cancelled in Flipkart app. How is it possible that my return is cancelled after I have returned the product back to the seller and pick up was completed successfully but I have not received my refund money. I have also Contacted customer care but no help is provided they are just saying that we will solve this problem by 48 hour but there is no solution provided by them,
This This can be a scam of seller or delivery boy or any other person I don't know about it but this is not expected by Flipkart I want my refund money back please provide me help.
