What’s this bill ? Why? Can you show me?

Who is charging you. Apple doesn’t charge for phones. Did you send one to Apple for a repair?

Where do you see the charge? If it is on your credit card or bank statement see this—>If you see "apple.com/bill" or an unfamiliar charge on your statement - Apple Support

If it doesn’t appear on a statement but it shows in an email it is probably a scam. See—>Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support

You will need to explain what you are asking about. We have no idea what bill you are referring to. We have no idea what product you are referring to. This is a user-to-user support forum; we don’t even know who you are.
