Club white smile NH SYSTEM APS FREDERIKSBERG DNK Took money from my credit card Not sure Internet

 I were asked to complete a Videotron survey about one month ago and in return I will receive an iPhone 6s plus as a gift which they had a limited amount of. I thought it was legit since that I had just take back my Videotron services. I never sign up to subscribe with a Clubwhitesmile.com for anything. Today I check my credit card statement and observe the unusual transaction. My credit card company agent gave me the email support@clubwhitesmile.com to request that I be unsubscribe and refunded . I receive a respond saying that I will receive answers to my questions in 24-48 hours and I can go to clubwhitesmile.com to unsubscribe which I tried but found out this it is not a website that is relative to this services.
