How to get money back
My child uploaded application “find me” and I deleted it at the same day and didn’t use it but now I get bill for month subscription. How can I get my money back???
Deleting an app does not remove any link to subscriptions. You need to follow these instructions.

Where there has been a genuine mistake, Apple will sometimes refund payments. On your receipt is an invitation to report a problem. Set out the facts and await a reply.
