Hello, I'm from Kosovo, would you like to stop me from making a purchase that I accidentally made in the Apple store, can you please let me out?

We are all Apple users, like yourself, in this community, so have no access to your accounts or details.

Also, we do not know:

what kind of purchase (apps, media, etc)

Eg: If money has been deducted from a credit / debit card etc: How to:

Request a refund for apps or content that you bought from Apple – Apple Support.

or

whether it was an online Apple Store or in store purchase: Help - Apple

or

whether the money has been deducted from an account, or is "pending".

So it is not easy to know where to direct you.

You might want to try phoning Apple

ie: in the country or region where you made the purchase:

See a list of Apple support phone numbers around the world:

Contact Apple for support and service - Apple Support

If your country is not listed: 

Apple Assistance:

Choose your country or region - Official Apple Support

All the best :)

PS: Other options for contacting Apple:

There is a "Get Support" link (online chat, phone, eMail etc.)

at the bottom of the websites listed below:

Subscriptions and Billing - Official Apple Support

App Store - Official Apple Support

iTunes - Official Apple Support

or
