Ring Protect payment

I have been charged for the Ring Protect payment on my credit card. I didn't give any payment details for this.The 30 days free access to videos etc has now stopped. But when I look at Ring Protect on the Ring app it says I have subscribed, my cc says otherwise.I have uninstall the app, reinstalled but still showing as no plan in place.Help!!! I'm not paying for something I can't access.
