Zurple review: Bogus charges and no idea how to stop it

I started to use the website www.zurple.com, but these ### started to take money from my account. When I noticed it, they already stole about $200. I tried to reach moderators or any other people from this company, but of course they ignored me. I tried to cancel the membership, but nothing. I wonder if there people who can help me to stop these withdrawals and cancel membership. Please post comments.
