Amazon India — Return and refund of the wrong items received.

Address:	Mumbai City, Maharashtra, 400037
Website:	amazon.co.in

I had ordered for one milton water jug 6, but the item delivered was Milton casserole set. Next day, again one item was deliverered, which I did not order. My family thought that there will be right item, milton water jug 6 and the amazon boy came to replace item. But, in the second box, there was also milton casserole set. Since, my wife opened the second item to check whether the right item is or not, I had to pay second time also to amazon boy. I requested for return and refund of one item online. But the second item has no online record either to Amazon or me. How can I get the second item returned and get my refund?
