Hi badette23,
welcome to the Apple (user-to-user) Community.
Re: apple wants to deduct me 779 instead of 579 pesos:
can some body will explain it ?
We are all Apple users, like yourself in this community. We have no access to your accounts or details. We'd like to help however.
Sometimes Apple may combine more than one charge in the same amount.
(Eg: maybe a family member made a purchase ?)
How to see what you were charged for:
If you see "apple.com/bill" on your billing statement – Apple Support
_______________________________________________________________
If the price of your subscription did increase:
Apple support have an article online that may help explain:
About subscription price changes - Apple Support
_______________________________________________________________
If needed:
After any excess money has been paid (not pending):
You could:
Request a refund for apps or content that you bought from Apple – Apple Support:
Else:
You might want to reach out to the Billing Support Team:
There is a "Get Support: start now" link (online chat, phone e-mail etc., or an app)
at the bottom of their webpage (link below)
Subscriptions and Billing - Official Apple Support
All the best :-)
