Amazon India — Item was missing and company not accepted that and not not giving refund

(Renewed) realme 10000 mAh Power Bank (Fast Charging, 30 W) Black I have orderd this product and Didn't get it i have received empty box with only empty rapper and bill
And I already filed complaint for this issue but not get resolution yet . Amazon company is refusing to give refund and is asking for evidence from me that if Delivery Boy has done something, then give the evidence. This is Amazon's responsibility and not mine and I asked Amazon for proof of investment, they didn't even give me proof. It was said that internal activities cannot do the show.
