Amazon India — Product Scam

I ordered an electronic device from the amazon shopping application on 4/04/2022 and i received my order on 11/04/2022. When i checked the order i didn't receive what i ordered. So, i complain to the customer care they told me that we need to investigate this situation we'll update you in 5 days. I'm waiting for 5 days. I also contact the Dealer and mail the dealer that i didn't received what i order. Dealer mail me that we accepted your return policies and initiate your refund but when i initiate the refund/return process it automatically cancelled and showing that the return is cancelled by the customer and when i talk to the amazon customer care again they said it's not our fault. We send you the actual product.
