Amazon India — samsung galaxy m31s not delivered but showing delivered

I have ordered galaxy m31s during amazon prime days on 6th sep 2020 and lenovo legion y540 on 7th sep 2020, they send me the 2 products with single tracking id on 14th i got the notification that my products will get delivered today but provided only a single otp. Delivery person delivered my lenovo legion 540 only and when i asked him about my 2nd product then they told me that i have only a single product of yours and asked the otp and after giving otp both products showing delivered. I have not noticed that earlier but on same day i noticed this issue and on same day i called amazon customer support for help regarding my product galaxy m31s but they told me to show some patience its just a scanning issue wait till 19th aug 2020. But till date i didn't got my product so i complained about that and amazon started investigating but they reported that the product is successfully delivered to the customer... So where is the product... I have not received my order... And they are denied for refund or any other compensation
