trying to cancel match.com subscription

I thought I already unsubscribed, but I checked because I never got a refund. In iTunes, it still says it is an active subscription. There is no button to unsubscribe, cancel, or turn off auto-renewal. It says it expires December 28, 2017. There are buttons to subscribe for 1 month, 3 months, or 6 months, and nothing below that where I could cancel or turn it off. Just a done button. What do I do to either check if it worked when I cancelled (3 weeks ago) or to cancel now? I looked online, and everything says to turn of the auto renewal toggle, but there isn't one. (This is match.com, not iTunes match)
