fraud way to compel people to buy product from website

i was working on my PC ansd suddenly a window open up and says that this a survey by chrome and just answer three 4 questions and you can win prizes. i clicked on questions and result came you are luckey visitor and choose one of the three phones, prices showing 499, 699. when i clicked on it it takes me to the page from where i can order that product than it takes me to the payment page( it seems like i am ordering something) after payment a massege came to my email it was not order confermation but it was saying that Contest Order Confirmed

Dear vibha bhatt,
You have successfully registered for shophunk contest .
Thank you for participating in contest.We will be updating you on the contest result by email .

If you are not the Contest Winner then you will get Rs.699 as your credits through which you can buy products in shophunk..

Amount has been credited to your Shophunk account.
Your Shophunk Transaction Id : 4453452.

then i realised that it is a fraud they are not even ready to give our money back they are compelling us to buy something from their website. i have written mail to them but nothing happening.

i want you people to do something so that they will stop this fraud. if their company is true they should tell buyers straight in the starting that this is a contest and you are not buying anything you are just registering yourself for the contest before taking payment. but they are doing fraud they are telling us till the end that it is a contest. if they have told this before i never enter in the contest they disguise the things and i hate this.

please do something i want my money back i dont want to take part in their contest and even i dont want to buy anything from this fraud website.what a bad marketing strategy to compel people to buy
