If your original purchase was with Apple we have no involvement or information about your subscription.
Apple will auto-renew your subscription unless you specifically opt-out. If you wish to stop the auto-renew you'll need to log into your iTunes account and go to your purchases section and switch it off. If you wish to cancel your subscription with Apple please also see the purchases section in iTunes where there should be information about how to cancel.
Once you've cancelled in iTunes you can subscribe direct to SOS via the SOS online shop and purchase our Digital subscription which includes website access to all our locked article content.
