But, I am concerned that you may have been scammed. Apple does not make many billing errors.

Could you have provided any potentially damaging information to a phisher/scammer? If yes, in your case, you'll need to follow up with the party that recorded the charges, e.g., your credit card company, Apple, etc. 

To be proactive, learn about phishing, scams, and Apple practices, etc., see:

How to identify scams related to purported apple notifications—per Eric Root.

“Apple will always address you by your name or the name they have on file for you, not Dear Customer, Dear Client or by using your e-mail address. The e-mail will be from @apple.com or @iTunes.com. E-mail addresses can be spoofed. You can go to Mail/View/Message/Show all Headers to see more. Apple emails won't have poor grammar/misspellings. Apple e-mails will never contain an attachment. Apple will never request personal information by email such as Social Security numbers, your Mother’s maiden name or full credit card numbers. …The only exception to the above I have noticed is if you order something from the Apple Store (apple.com), your receipt will be addressed to Dear Apple Customer. That is a receipt for a purchase you initiated.”
