Gifts-To-India.com — wrong product delivered

HI
My Name is Neha and i have bought a cycle online from a website http://www.gifts-to-india.com/ for my niece on 19th july. First they have not got it delivered it till 24th july 2012 but after calling them and asking about it they said it will be delivered soon so they finally did on 25th july night time.
Though the product was deliverd but the item which i had ordered was not the same which they delivered. On my repetitively calling and sending the photographs they have not taken any action and not even they are telling what they will do instead they have mentioned that "since the product has been delivered so they cannot do anything right now".

website is http://www.gifts-to-india.com/
my order reference number : GTI-[protected]
Amount paid its Rs 3199.

I am happy in both ways if they exchange the product with the one i have ordered or refund my money.
Thanks
Neha Aggarawal
