Nonrecurring paid subscriptions renewing anyway
 

Okay this is going to take a bit of back story. I used to have a co-owner on my site and when we first set it up, we set up a paid subscription system. The subscription was for a year, but after a year, we got an email from a user who was no longer very active. He had been charged for a renewal. The co-owner handled it and changed the subscription in the control panel to no longer be recurring. Now this year the same member is emailing me with the same problem. He got charged the $18 but when I look in the admin panel, it says his subscription isn't active. When I look at the subscription, it says it is not recurring. What am I missing and what can I do to make it stop? We honestly don't even need subscriptions right now. Would deleting all of our settings stop this problem?

Btw, I can't even find any place where a member would go to subscribe. Should that be in their user cp somewhere?
