I was charged twice for my monthly iCloud storage

Hi jafafrm561,

welcome to the Apple (user-to-user) Community!

Re: "Buying storage : I was charged twice for my monthly iCloud storage "

As we are all Apple users, like yourself, in the community, no-one here has access to your accounts or details in order to check this out for you. We'd like to help, however.

If you recently began, or upgraded the iCloud subscription:

Wondering if you were charged for the current month, and then for the month up ahead ?

How to see what you were charged for: If you see 'apple.com/bill' on your billing statement - Apple Support

If needed:

Request a refund for apps or content that you bought from Apple - Apple Support

or

Report a problem: https://reportaproblem.apple.com/?s=6

or

You can get in touch (online chat / phone / email etc.) by using the "Get Support - start now" link on their webpage

either with iCloud support : iCloud - Official Apple Support

or

Billing and Subscriptions Support Website : Subscriptions and Billing - Official Apple Support

All the best :-)
