Shoppingsworld.com — Didn't delivered the product purchased

I got a call on 9 June from shoppingsworld .com that there is a scheme going on on there website n I can win assured gift of laptop, LED or holiday trip etc. if I make purchases from there site. When I purchased a product they told me I had got a holiday trip so I said ok. They said I will get a confirmation mail n I got it the next day saying my merchant reference ID is 6002 n my EBS payment ID is 37978550 and I will get my purchases in 10days. But I didn't received any thing. Then I googled abt the site n came to know its a fraud. Please tell me what shd I do to get my money back n also nobody else get duped...
