Graze.com - BAD IDEA

Graze is a website where they bill you every week for bunch of nuts that they'll send you.

I got a free code and when I tried it, of course Credit Cards are needed. After completing everything, I know how this works so I cancelled the next box which will charge me $11.99. Little did I know it also cancelled the FREE BOX. What comes free if theyre gonna force you to pay the next when you only want to try it?
I erased my CC's and will never even try to come back. 
Ps, they don't even have a number to call in the website.
Good Luck!
