If you were told you wouldn't be charged but would, you can always reverse the charge with your credit card company. I have no idea how that would play out.
Might not be worth the headache for $25 but if it's the principle, you could consider writing a letter to CR saying that you were charged for something to which you did not agree and you are contesting the charge with your credit card company and if they wish to discuss it with you prior to that happening they have two weeks to give you a call before you do it. Politely, of course
