Amazon India — refund not given after a-z guarantee claim

Website:

www.amazon.in

I ordered a sendai glossy metal bed from original bed co. On amazon. The bed was defective (See photo). It was impossible to assemble as two parts were not aligning and screw was not fixing. It is now more than 10 days since i have asked for return and refund and neither the bed has been picked up nor the money has been returned. Amazon is sending me threatening emails that the claim will be cancelled if i donot provide them information about the return of the product. They are putting the responsibility of returning a damaged product on me, the customer, who has paid for the product fully in advance. They have refused to publish negative reviews of the product and the product continues to show on amazon with 100% positive reviews raising suspicions of the involvement of an insider at amazon in promoting this product.
