WWhichever Credit card you have inyour iTunes account it's kept on file. So if it's Amex for example than you are using that credit card when you pick another storage. Then unless you cancel that storage you will continue to be charged for that extra space each month!
Yes, I know that. But the issue is the OP has not seen any charges on his bank account.
Unless the payment method associated with the account is a Debit card, there would be no changes visible in the bank account directly.
Maybe you did not mean to reply to Me, but to the OP?
