I cant get a refund because my kid was using my phone

Request a refund for apps or content that you bought from Apple - Apple Support

The people responding on this support forum are users like you and we only know what Apple says in its documentation and what our own and other users' experience tells us. Apple does not have much on its criteria for refusing refunds. Here are two sections from the September, 2020 Apple Media Services Terms and Conditions - https://www.apple.com/legal/internet-services/itunes/us/terms.html

- "All Transactions are final."

I understand this as meaning Apple is starting from a point where any refund is considered an exception. They can simply say no without having to provide a reason. I understand this can be frustrating but by using the service you agree to the terms.

- "From time to time, Apple may refuse a refund request if we find evidence of fraud, refund abuse, or other manipulative behavior that entitles Apple to a corresponding counterclaim."

You can see if the terms are different for where you live by clicking on this link https://www.apple.com/legal/internet-services/itunes/ select your location and then your language.

If you feel you want to discuss a refund request, try to contact a live person using a telephone or chat request.

If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
