Amazon - Received an Empty Box from Amazon

I ordered Oneplus Buds Z from Amazon on **-Mar-**** and Recieved it on *-Mar-****. When I Opened it was Empty.
As i said i ordered it on **-Mar-****, i observed Even after *-* days the packaging glue was sticky & stretchy.
So, I called Amazon customer care as soon(in * minutes after delivery) as i got my parcel & raised a Complaint About my order.
Amazon Customer Executive told me to contact them back in * days. they will have to escalate it to some other team and do an investigation.
but, I kept calling daily to know the status of my Complain. After * and half days, there was no update on the status of my Complain.
so, I contacted Amazon after * days & they said that our Amazon Investigation Team denied my claim. It is funny that overnight they completed my Investigation.
how can someone come to a conclusion without any proper investigation.
They didn't call me, They didn't ask me about any detail. They didn't do Anything.
I'm a Amazon Customer from almost * Years. I have ordered a lot till Today & never raised an Issue like that.
I mailed Amazon Customer Support on **-March-**** & I was told that we are creating your replacement order and when i asked will the delivery agent accept my empty Oneplus Buds Z Box? Then they said You do not have to return the item & on **-Mar-**** at the time of Delivery, the Delivery Agent denied to deliver it. After that i call Amazon Customer care and again they said we cant give you any refund or replacement. Making U-Turn from what they've mailed me. Now, they are also Ignoring me on email on cs-reply@amazon.in. This is so pathetic. It's been almost ** days I'm Calling & mailing & I'm getting mentally disturb by all this. I'm also Attaching Some Screenshots. Please See it.
