However, you may be the victim of a common scam where criminals pose as major retailers. It happend to us and the retaeila was not able to fix it. See:
If you see 'apple.com/bill' on your billing statement - Apple Support
The most important part of that article is "View your purchase history." If Apple does NOT show a record of the charges in your history, it is very possible that scammers have gained access to your credit card or bank number and are pretending to be Apple. It happened to us.
If that is the case, only your CARD ISSUER or BANK can remedy it. Apple cannot as they dod not make the charges.
If Apple’s purchase history shows the purchase, continue with the instructions in that article.
