I’m already pAying .99 cents a month why do I have to pay more?

Assuming you are asking about iCloud storage, 99¢ a month buys you 50GB of iCloud storage. If you need more than 50GB you must pay for more. The next step up is 200GB for $2.99 a month.

If you're sure that those charges come from Apple (check your bank statement very carefully, ignoring scam messages that might be addressed to your iPhone), start reading this support page:--> Subscriptions and Billing – Official Apple Support, and check each of the first 3-4 sections.

If you cannot find the information you were looking for, please contact iTunes Store Support Team directly and explain your problem, using this specific link:--> Apple Support
