My Credit Card Billed After My Account Was Cancelled

Back in Late May or early June, I signed my Husband up on Classmates.Com in order to find out if any Class Reunions were planned. He received emails from numerous classmates, a few he knew and others he did not. This GOLD Account was cancelled because he / we could not attend the Reunion because Our Son was getting Married. I did receive an email confirming my cancellation and as of Fri. 10/16, I have a $15 Charge on my Credit Card Statement. I WISH FOR THIS $15 TO BE CREDIT BACK. I NO LONGER DESIRE BEING REGISTERED, HAVE NOT INTEREST IN CLASSMATES.COM I have tried to cancel this by phone and the rep that I talked to said,"he needed to talk to my husband because he was the Classmate Signed On. This is billed to ME (MY NAME) on MY (CREDIT CARD). I think someone needs to talk to me. I do not appreciate the way you do business. I Wish to be FOREVER CANCELLED.
