I accidentally bought iCloud storage, is there a way to cancel it and get a refund?

Hello micayla52,

Thank you for using Apple Support Communities! I understand that you're wanting to know if there's a way to cancel and get a refund for an iCloud storage plan that was accidentally purchased.

To downgrade to the free iCloud storage plan, follow the steps here:

Downgrade your iCloud storage - Apple Support

Use the contact link in the section below to see if this purchase is eligible for a refund:

"* Contact Apple within 14 days of an upgrade for a refund. Partial refunds are available where required by law."

Cheers!
