Best green tea health Fraudulent charges Estero Florida

Got a charge from this company, and called the number provided. The woman answered and said that she worked for a company that managed a lot of Internet sites, even though the website for best green tea health says its their official number. She said she deleted my acct., which I never made, but wouldn't reimburse me the money. She said I'd have to call back in 3-5 days And wouldn't let me talk to a manager. I cancelled my Visa card in fear that my acct. was compromised. I looked up the IP address of the company and found out its managed through amazon web services. I recently made a purchase on amazon with that card, and I'm widening if anyone else that's had this issue, also made a purchase from amazon shortly before getting the $49.95 charge? Beware of this charge, and file a claim with your bank as soon as possible. The website shows 3 different addresses for this company, which includes Florida, UK, and Scotland.
