I have charges I don't recognise

If the invoice is not from Apple, was the money deducted by a stranger?

Contact your bank, they can find out who (name, address & account number) has collected the amount from your bank account, and when.

Depending on your bank, they can collect the amount back within 30 days.

Also report to the police.
