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, 2022 Apple Media Services Terms and Conditions - Legal - Apple Media Services - Apple
- "All Transactions are final."
- "From time to time, Apple may suspend or cancel payment or refuse a refund request if we find evidence of fraud, abuse, or unlawful 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 Legal - Apple Media Services - Apple 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.
Click here --> Choose your country or region - Official Apple Support Select your country, then a product. 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.
