To cancel Selecta billing from iTunes, follow these simple steps on your iPhone, iPad, or Apple computer:
Canceling on iPhone or iPad:
Open Settings: Go to your home screen and tap Settings.
Tap iTunes & App Store: Select iTunes & App Store.
Select Apple ID: Tap your Apple ID.
View Apple ID: Tap View Apple ID. You may need to sign in.
Manage Subscriptions: In the Subscriptions section, select Manage.
Cancel Subscription: Find Selecta and select Cancel Subscription.
Turn Off Auto-Renewal: Your subscription will end at the end of the current billing cycle.
Don’t See Your Subscription? If your Selecta subscription doesn’t appear but you’re still being charged, make sure you’re signed in with the correct Apple ID. Sometimes, you might be using a different email or Apple ID.
If everything is correct and you don’t find the subscription in iTunes, you may have subscribed directly on Selecta’s website and not through iTunes.
