How to delete a pending purchase?

Hello Barbwitch,

Thanks for asking the Apple Support Communities for help with a pending charge.

It sounds like there was an issue with your billing method. Correct the issue or add a new payment method: If your payment method is declined in the App Store or iTunes Store - Apple Support

One the charge goes through, if there was an error, you can request a refund: Request a refund for apps or content that you bought from Apple - Apple Support

"If the charge is pending, you canʼt request a refund yet. After the charge goes through, try to request a refund again."

Thanks and have a wonderful day.
