Q: I had an app auto-renew and I don't want it.

If it was billed through iTunes the following has instructions on how to cancel: View, change, or cancel your subscriptions - Apple Support

This helped me cancel auto renewals, but it says my subscription is good until July 12, 2017. I don't want the app, I want my money back.

We are fellow users, these are user-to-user forums, nobody on here can potentially refund you. Try contacting iTunes Support and see if they will refund or credit your (but purchases are considered final) : http://reportaproblem.apple.com
