This is a user-to-user forum; just us users here. We don’t know who you are and don’t have access to your account.

Here is a one-stop link for billing questions→Subscriptions and Billing - Official Apple Support. You can review your purchase history, check a specific purchase, manage subscriptions and request refunds.

If you were charged by Apple for something there are a few possibilities:

• You purchased it from the app store (or subscribed to a service) and forgot you did
• Someone you share your phone with purchased it from the app store
• Someone you share your Apple ID with purchased it from the app store
• If you have a family sharing plan, someone in your family purchased it from the app store
• Your Apple ID was hacked and the hacker made a purchase from the app store - for this one see ➡️  If you think your Apple ID has been compromised - Apple Support
• You were not actually charged for anything; the message you got was a scam to steal your identity - see ➡️  Avoid phishing emails, fake ‘virus‘ alerts, phony support calls, and other scams

The bottom line is that Apple never charges you for any purchase without authorization. So someone with access to your account must have made the purchase or subscription, if it wasn’t a scam message.
