I think all you have to do is call them and they will cancel it immediately and you should get no more charges on your account. At least that's what happened with me they were very nice and polite about it.
A simple call. They delete your payment info immediately and no further payments come out of your account. You'll be paid up through the date specified of your last payment.
Call them
I believe all you have to do is go in and they can cancel your membership. Super easy
