Classmates, aka memory lane, kept my information and renewed my membership without my permission.. I joined this 2 years ago and went through this last year also,  did not rejoin last year and did not want to join this year. The place is a rip off. I do not use it, do not want to use it.  I don't believe a company should be able to keep your info without your permission, much less use it. I asked for a refund and was told they had a no refund policy.  I have filed a dispute with my bank and will be changing my card number.
