Amazon India — ordered item returned without my knowledge

Website:

Amazon.in

I ordered two items. One item was delivered today without any problem. I got a message saying item will be delivered on 16th by the agent for the second item. After 3hours, i got another message saying that the package is being returned to seller because it was refused at the delivery address. But nobody contacted me regarding the delivery. I tried to contact the agent but he wasn't lifted my calls and not responding. I have sent message also. I contacted amazon also, but of no use. I planned to give that item as a gift to my wife. Because of the carelessness of delivery agency and amazon, i felt ashamed without my mistake.
