Scam marketing to sell products

Testoextreme is marketed using celebs or sports people' names/pics , When you accept their free samples , first you get charged for delivery ,which you then decide to pay , but then they immediately add another different product to your shopping list + delivery and you unknowingly also automatically will get billed every month thereafter for additional supplies without you having agreed hereto ,because when you try to read their terms & conditions ,, you get a message saying " page not found" Scam ????
