Citi Cards offers a free 30 day trial of Credit Notify, who monitor your credit reports etc. I was assured that if I called within the first 30 days that I would not incur any charges.
About 3 weeks after signing up, I received my initial report and called immediately to cancel the service to avoid any charges. I spent 40 min with a representative who at first attempted to salvage the account, and then assured me that the account had been closed.

Today, May 29, 2009, I was reviewing my credit card statements and noticed 4 months of charges from Credit Notify of $12.95 each. I called CreditNotify to rectify this, and as they gave me no confirmation number and claim to not have any notes or record on the account of my prior phone call they refuse to honor my cancellation. The "customer service representative" was incredibly insulting. She continually interrupted and placed me on hold several times when I would insist that she let me finish my sentence. She claimed that she was the highest supervisor, only to learn after that this was not the case.

This service is TERRIBLE. They are frauds! Avoid at all costs.
