Need to terminate

I joined on May 2, however after reviewing the site it won't help me any.  I am a single parent of two and when I went on the tour the sales rep made a powerful presentation that looked like it would save me lots of money on anything I wanted to buy.  That turned out to not be the case, the items were just as high a in the store.  The sales rep was very misleading.  I need to terminate my contract, however I was told that I could not.  Is there anything I can do to get my money back and not have them drafting my account monthly.  

Thank you in advance
