Refund unauthorised transactions

If your "unauthorized transactions" are not revealed after consulting either If you see "apple.com/bill" or an unfamiliar charge on your statement - Apple Support, or See your purchase history for the App Store, iTunes Store, and more - Apple Support, report them to your card provider as fraudulent.

Actually this is very interesting to dispute because I am a UK resident I would not go on YouTube and pay for a subscription which was so small that I didn’t notice and also do not do banking online I don’t have paper statements

If you did not make the "unauthorized transactions" your fraud dispute should be made with your card provider, not Apple.

Correct but I’m a victim of fraud? I’m sorry American? Can’t believe it

The implied complexity of your situation transcends the capability of anyone using Apple Support Communities to be able help you with your situation.

You should instead be contacting credit/legal/law enforcement authorities.

Have you considered cancelling the credit card and then ask that a new card be issued.
