Amazon India — theft my product

Address:

Bajanai Kovil Street, No 76, 603402

We ordered a "samsung eo-bg920bbegin bluetooth wireless in-ear headphones with mic (Black-sapphire) upon goods received, the delivery man run away immediately, and when we open the package immediately, the box were damaged and it comes with waste door magnet instead of bluetooth headphones. We contacted amazon india and they mention they will investigate. After several emails follow-up and calls (More than 5 days with no response), we contacted amazon india via chat services. After the chat, they directly inform us that they have checked internally and packages were delivered accordingly.
