Re: Money debited one day before subsciption due date
Seems we always need to cancel a free trial / subscription at least 24 hours before it expires in order to not be charged for the following subscription period:
Apple support have articles online that can help to guide us:
How to see what you were charged for: If you see 'apple.com/bill' on your billing statement - Apple Support
What to do: If you want to cancel a subscription from Apple - Apple Support and if you can't find the subscription.
Canceling subscriptions is slightly different in some countries and regions.
Learn about special circumstances for Germany, Israel, South Africa, and Türkiye.
If money has been deducted (not pending):
Request a refund for apps or content that you bought from Apple - Apple Support
If more info. / support / contact is needed
Billing and Subscriptions Support have a website online:
Find answers to your questions about purchases, subscriptions, payments, and billing:

All the best :-)
