Advance Wellness Research was offering a free trial of their product Acai Berry online. I received the product for free and just paid the shipping fee. While I was checking my credit information, I learned that I have an outstanding balance from this company of CAD $100.63. I haven't even see the effect since I started taking their product and now I am being billed for this item. How could i cancel the billing they sent through my credit card company? What is the email address that they are using?
