Paytm - Ordered Iphone X but Received an Iphone 6s body filled with mud in the package from Paytm

I ordered an Iphone X ** Gb Silver color via order no. ********** on **/**/**** and received the package on the same day. Inside the box was an iphone * body filled with mud with screen tapped to it. I have already shared an unboxing video of the same with paytm care & also the pics they have asked me to share.

Despite providing enough proof I have been told by paytm care via mail that after their investigation they have found that correct product was delievered. Their mail said that no empty box was delivered when I never complained about an empty box.

This is the mail i have received from Paytm-

" Dear Lalit,

This is regarding your concern for receiving an empty box for order ID **********.

We launched a full scale investigation and our checks have confirmed that correct product was delivered to you. Therefore, we will not be able to proceed your request further.

Hope this helps.

Sincerely "
Whenever i ask them to share the details & facts of the investigation or grounds on which they have established that correct item was delivered they just keep sending me the above mail again and again.

This is despite i am having the video of original unboxing of the package i got. the video is available on the following link:
