That's what I did with 24 Hour Fitness. I had to cancel in person, which is ridiculous, but the guy told me that because of the way their system works, they will charge me for the next month too. When the charges showed up a month later, I use chargeback to refund the money and that was the end of it. Their system supposedly being slow to process isn't a reason for me to be charged another month; one shouldn't be rewarded for incompetence. I was ready to fight them on it because nowhere in the agreement did they mention charging me another month after cancelation but they let the chargeback stay -- probably because they know it's baseless and was hoping people won't bother fighting them.
