App refund

Hello there sathik112,

Thanks for posting here on the Apple Support Communities! This is a place where other Apple users can submit questions or respond to others to help lend a hand. Let's take a closer look as we do our best to provide some additional insight.

In order to follow up on your prior refund request, you'll need to contact Apple Support directly. However, do you know if you had any Apple ID credit on your account? If so, then check your Apple ID balance to see if the difference was refunded there as Apple will always charge your Apple ID balance first: Check your Apple ID balance

Check your balance on your iPhone, iPad, or iPod touch

1.Open the App Store app.

2.Tap your photo or the sign-in button  at the top of the screen. You might be asked to sign in with your Apple ID.

3.If you have a balance, the amount appears. If you don't see an amount, you don't have a balance.

If you need to contact Apple Support: Apple Support - Get Help

We hope this helps get you pointed in the right direction.

Take care.
