Amazon India — defective piece sent with no accessories and not coming to take the product back

Address:

Pune, Maharashtra, 411061

I have ordered the the order #[protected] n. I got the order on 31 st. On same day, i had asked for the return as the product is defective and missing the accessories. I called many times to customer care. I posted on facebook, twitter. But no body is coming to pick up the product. Today, 7 days over and nobody came to pick the product. This is really irritating

Even they blocked my phone number and chat services as well. Attaching the screen shot for the same.

Now i am frustrated. I dont have any option to contact amazon. I am really feeling pressure. I think, amazon does not want to return my money.
