See the review below, everything they said is true and applicable to my account with them as well. Also, the only way to cancel a subscription is to call, and they only answer the phones between 7am-12pm. That is, if they answer them at all. And don't call on a cell phone, the minimum hold time is 30 minutes.
Once you get your subscription cancelled and the billing straightened out (which took about of 5 months in my case and resulted in me just cancelling my debit card and getting another one), you can look forward to being hounded night and day by their reps, asking why you cancelled and if you're interested in renewing your subscription. I moved out of state and for FIVE YEARS they kept calling me every two weeks asking me to renew my subscription. I kept telling them that I wasn't even in the state and two reps actually suggested that I subscribe anyway. Seriously?!!?
