Why my purchase could not be completed?

Hello Opragold,

Do as it directs, go to the URL and follow the instructions:

www.apple.com/support/itunes/ww/ --> https://support.apple.com/country-selector/itunes > select your country > Contact Support > Contact iTunes Store Support > Purchases, Billing & Redemption

Did you contact iTunes Store support using the link and then the path I provided earlier?
