I too am planning to cancel the membership before it is due to be put on my cc....
we plan on canceling it, and then in a few days attempting to use it, to see if it was really cancelled or if it is still active... if still active, we will call back...
also, when ever you call in, they always give you their id # and name... be sure to keep track of who you talk to when canceling!
and of course, be sure to ck your cc bill to be safe!
