Did you check your purchase history, to find out, for what you are charged for?

If you see apple.com/bill, itunes.com/bill, or an unfamiliar charge on your statement - Apple Support

If you are getting mails, containing this information, they might not be genuine mails from Apple:

Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support

if you just get some mails claiming you're being charged then read

if you can have your bank verify apple are withdrawing money from your account then

if it's you who are withdrawing it then I got nothing
