I would like to subscribe with Lynda.com, but I am worried about not being able to unsubscribe and being forced into paying for constant subscription?

I have had a terrible experience with Fandango.com awhile ago, and despite the fact that this is a totally difference company, it made me terrified of online subscriptions. Fandango.com kept billing for a subscription even after I told them I didn't subscribe and don't want to subscribe. So how safe is Lynda.com?
