Complaint Review: Netflix

I signed up for a Free trial Streaming videos.  I watched a couple of movies.  I couldn't use my computer while watching a movie so I cancelled before my free trial was completed.  On Dec 5th I got an e-mail saying I cancelled.  On Dec 14 Netflix drew 8.61 out of my account for monthly fee.  They say I had a monthly movie subscription.  I never signed up for one, I had the streaming videos & I have not received any movies from them.    I am asking for a refund of $8.61 & a cancellation of any & all accounts
