>>Cancellation of Learna Pro subscription and unwanted charges
Hello,
I would like to permanently cancel my Learna Pro subscription. It appears as expired since October 29th, yet Apple continues to attempt to charge the amount of €17.99.
I no longer wish to use this subscription and request that any outstanding balance associated with this unwanted renewal be reviewed and cancelled.
I wish to keep my iCloud+ subscription.
Please help me resolve this situation and allow me to remove my bank card from my Apple account.<<
In most cases, you will have to cancel your subscription at least 24hours before it automatically renews.
To cancel a subscription you made via Apple, go to Settings -> Your Name -> Subscriptions -> select the subscription you want to cancel -> tap ton "Cancel Subscription".
You can also use the blue link in the related article to start the process on your computer browser:
Cancel a subscription from Apple - Apple Support
Anularea unui abonament de la Apple - Apple Support (RO)
If you want to request a refund, you will have to pay the subscription first and then follow the steps in this article:
Request a refund for apps or content that you bought from Apple - Apple Support
Solicitarea unei rambursări pentru aplicații sau conținut achiziționat de la Apple - Apple Support (RO)
But, not all requests for a refund are granted by Apple. This might also be the case, when a user did not cancel the subscription in time.
