Vista Print - Business Max 123 Business Max 123 Charged my credit card every month without my approval Internet

I started a new business and ordered very nice stationary from Vista Print.  Apparently, by making a phone call to my business number, this Biz Max (Business Max-123) felt they received authorization to charge my credit card that I used to purchase my office stationary.  I thought the charges were for a reputable on-line advertiser that I use until I called the phone number.  I cancelled the membership and notified my credit card company right away. However, I've had these charges for 6 months!  Fool me once...When I looked up Business Max it is a service that provides discounts to services like FTD.  I never received any discount "coupons" of any kind and I know I would not have authorized a monthly charge for something like that. I think they took my credit card information from my order on Vista Print.  I am really disappointed.
