Firstcry.com — Wrong product delivered and firstCry is not taking back

Order number 6386332UVJD42E23E Wrong product shipped-

This is in regards to the return of the product (PinkCow Pearl Detailed Sleeveless Net Drape Gown - Light Blue). I had ordered a Dress for my child and I received a ladies handbag without any tag. I mailed so many times and talked to customer care executive but they are neither refunding my money nor delivering the product which I ordered. Does this give them right to harass the consumers like this.

I need my money back as its my hard earned money and would not let any online site cheat us like this.

I will go to any level to get my refund.
