Why charged me twice from my visa card for 50 G

Do you use multiple Apple ID?

Check -> Go to -> Settings -> your name -> iCloud -> if you see 50 GB (or 200 GB or 2 TB) then you have an iCloud subscription.

If you have an iCloud subscription, you will receive a monthly bill from Apple, check your email box.

You pay monthly for iCloud storage.

If you see an unexpected charge

You can request a refund* for a purchase that you don't recognize, but you must pay for the purchase first. You can also cancel a subscription if you don't want to continue it.

*You must request the refund within the refund period.

Refunds are not guaranteed. For more information, see the Terms & Conditions.
