Firstcry.com — Product is not delivered and company is not taking action

I have placed order on 15th on July for my friend and order contained 6 items. On 19th first item delivery happened, but it was only empty box with invoice inside it. I raised concern to customer care team over call and email. But in the end they are saying that as per there investigation delivery on item happened. So it is now loss of my money. I would like to get my money back or item should get delivered.
