No delivery no response

I placed an order on 9th Feb 2023. I received an email that said product was delivered on 14th Feb when intact nothing was delivered. I complained to the delivery partner, shoppers stop customer support, chat support, email support, phone number and every platform possible. I got no response. My order value was more than ₹7.5k and now there is no information or help from anybody. It's 27th Feb today and everyday I am complaining. All in vain.
