Charges on my bank statement iTunes but not showing up on My iTunes

Click on this link to read what to do "If you see ‘itunes.com/bill‘ or an unfamiliar charge on your bank, credit card, or debit statement" --> https://support.apple.com/HT201382 Note, if you are a Family Sharing organizer, purchases or subscriptions made by another family member may be charged to your card but will not appear under your purchase history or subscriptions. Ask family members about those or check your receipts.

There are multiple topics covered in the article I linked. One of them includes card fraud. Apple does not handle that, though they can tell you for sure if it is nothing they are charging. I would make sure you go through all the various tools in the link I provided since they will likely ask you if you have checked yourself first.
