My receipt says:

Payment Method: Store Credit
Item: 10 GB storage plan, billed annually $20.00
Total: $20.00
* You may contact Apple for a full refund within 15 days of an initial upgrade purchase or within 45 days of a subsequent yearly payment. Partial refunds are available where required by law.
But I cannot find an Apple contact. Thank you for any help.
