My purchase is for $4.99 why are you trying to get$29.97 from my account I don't owe you anything.

No one here can give e you an answer. No one here is an Apple employee, just users like yourself. These forums are not Apple support and Apple does not respond here. So we do not have access to your account information, period.

If you see 'apple.com/bill' on your billing statement - Apple Support

Hi, I’m sorry, for the confusion you’re experiencing. But you’ve posted in the support community. Everyone here commenting is an end user like you. Apple support is not here. You can reach official Apple Support by calling:

1-800-MY-APPLE

again, sorry for your experience.
