Hello,
Thank you for reaching out, an apple support agent should be able to guide you to purchases related to your appleID by guiding you through settings.
View your purchase history for the App Store, iTunes Store, and other Apple media services - Apple Support
On your iPhone or iPad
- Open the Settings app.
- Tap your name, then tap Media & Purchases.
- Tap View Account. You might be asked to sign in.
- Tap Purchase History.
Apple Support doesn't have you check your purchase history by opening your banking app. If you received a Case# in your e-mail you should be able to click on it and connect with an agent who can see that case and how it was handled, you may request to leave a complaint which are reviewed. You can also check near your case# email for a survey that should be tied to that agent. Please note that if you reach out again to submit a complaint and receive another survey, that survey will be for that new agent.
