Subscriptions and Billing - Official Apple Support

Does the website offer any Support info?

If it was done thru Apple, you can call Apple and ask for help to arrange a refund. I have done this with a Time subscription.

If not via Apple but with a credit card, the CC company can help (number is usually on back of CC).

Please return here with what you did to resolve the problem. Others may need that info.
