robbing my bank account

From May  2008 to May 2009 Network Agenda has robbed my bank account of $129.35 by charging unauthorized $9.95  a month for 13 months. I have never ordered nor recieved anything from them. How can I stop this from happening? How can I get a refund from them? Who are they and what do they sell? Thanks. Let's all keep after them until they are stopped legally.
