Hello , My master card is linked to some site and I made a payment of 27.97$, I did not use this amount and please help me to return the money.The bank of my country that I use "Bank of Georgia" contacted me and told me to inform you about this

First see if you can identify the charge:

How to see what you were charged for

1. To see your purchase history, go to reportaproblem.apple.com.
2. Sign in with your Apple ID.
3. A list of purchases appears. To see family members' purchases, select the Apple ID button and choose a family member.
4. To see the full receipt including tax, tap or click the date. Multiple purchases, including subscriptions, might be grouped onto one charge.

If the charge is for a subscription that you no longer want, you can cancel the subscription. Find out where else you can view your Purchase History.

If you still can't identify the charge

Can't find a matching charge at reportaproblem.apple.com? Find out if you used another account to make a purchase.

1. Search your email for the words "receipt from Apple" or "invoice from Apple".
2. Look for a receipt that matches the amount that you see on your billing statement. 
3. On the receipt, see what was purchased and which Apple ID was used.
4. Check if the Apple ID in the email is different than what you used to sign in to reportaproblem.apple.com. If it's different, use this Apple ID to sign in to reportaproblem.apple.com and review your purchase history.

If you checked reportaproblem.apple.com and your emailed receipts and you're still not sure why you were charged, contact Apple Support.
