Silverthorne Publications Inc. Didn't honor 1 year money back guaratee. Las Vegas, Nevada

On 2-01-2010 I ordered The Neural Strategy, a Roulette betting stetegy.  On 2-02-2010 I requested a refund.  I had to email them four times to get a response.  They finally replied saying they would refund my money they would refund my money within 5-7 business days.  Here it is 2-18-2010 and no refund.  They clearly offer a 1 year money back guarantee on their website.  They will no longer return my emails.  It's unfortunate ther are unethical companies like this company doing business on the internet.  I would recommend nobody do business with Silverthorne Publications unless you don't mind getting junk and don't mind not being able to get your money back.
