That's a scam site. The official site is here:

I hope you didn't purchase anything from them. If you did try to contact them and cancel your subscription. Then contact you bank/cc company and let them know that you were scammed and dispute the charges. A lot of those sites like to tack on additional charges for things you didn't order.
