I LOST MY MONEY RS. 2499/-

PLEASE HELP ME HOW TO GET IT BACK.

I have received a call 3 days back from the number 9205569818 , and was presented with the details of winning an Activa 4g  and sony headphones, rayban glasses and a scratch voucher if I pay them 2499 registration fees.

Whether company is Fraud or not I'm not sure but just had a concern so wanted to raise the issue.

And the bigger problem is that, the Company obtained my transaction details about what I bought ,when I bought and my Personal details as to my Current Residential Address and Phone number with Name.
