How to request a refund for my purchase?

The link provided in a previous post is for items from the app or media stores. Some information was removed from your post because it contained private information, so I have no idea what it was you purchased. Since you say it was in original condition (apps don't wear out) that makes me think it was some kind of hardware. Click here to read about Apple Store Returns & Refunds--> Returns & Refunds - Shopping Help - Apple

Here's how to request an app or media refund from Apple (From: Request a refund for apps or content that you bought from Apple - Apple Support - see the article for more detail.) If you bought this in the EU from a third party, see: About purchases not billed through the App Store or the App Store’s In-App Purchase system - Apple Support instead.

1. Sign in to https://reportaproblem.apple.com

2. Tap or click "I'd like to," then choose "Request a refund."

3. Choose the reason why you want a refund, then choose Next.

4. Choose the app, subscription, or other item, then choose Submit.

If you were charged for a subscription that you no longer want, you can also cancel the subscription using the directions in this article --> If you want to cancel a subscription from Apple - Apple Support

Read this support article for information about how long it takes to receive a refund (if you are granted one), and how to check the status of a refund for apps or content that you bought from Apple --> Check the status of a refund for apps or content that you bought from Apple - Apple Support

Hello,

You can view all of your subscriptions and purchases with this link, and request a refund yourself:

Good luck.

You can escalate it to report a problem.apple .com, if they refuse to help, then see if you could dispute the transaction with the bank.
