You can only cancel by phone (not online the way I signed up) and only by day when the call center is open (again not the way I signed up at night). She needed everything from my ss to my address.
The lady was very yenti with all kinds of questions when I told her I was closing the account. I told her nothing but I hope they don't trap people into long term deals by the answers they give. (Like the 3 month lock in:))
