Wooe — Internet fraud

They offered the cashback on purchase of md/ms pack worth rs999/_ after so many mails and complaints they returned it in there site wallet and made the limit of 1000rs/_ for bank transfer. There page said send the referal link for registration and you will earn 20rs/_ within 24 hrs. I referd the code to my friend he registered using the referal code send.
Its been more than 48 hrs but i didn't earn any rupee and still my 999/_ are in there wallet. I emalied them many times but all are in vain they haven't responded to single email yet
Kindly look in the matter.
