This website is fraudulent.
They tell you that they need credit card details but promise not to charge you. Then, AFTER you enter the details they say there is a fee for cancellation. Also to get you to sign up they promise that they have ebooks that they don't actually have.
I am going to inform my bank of this as well to make sure they stop processing payments from this site.
