GreenChef should be called GreedChef.
GreenChef requires you to enter your credit card before you can even see the menu. Even if you cancel right away, they still charge you for the first order, and getting a refund is almost impossible. They will fight you for a half hour before they give in. I finally had to have the charge reversed on my card. This is fraudulent and misleading. Nowhere in the terms and conditions does it say you cannot cancel your subscription to cancel all orders. I was in time. Their charge was put through the day after I cancelled. They are getting away with stealing money.
