Apple purchase

If it also says to contact iTunes Support you do as instructed and contact iTunes Support : http://www.apple.com/support/itunes/ww (click on your country's flag, the country where you live, and which is therefore the country on the account ; click on Contact Support towards the top right ; click on Get Help under 'Talk To Us’)

Try a different browser / computer / network, or try https://www.apple.com/emea/support/itunes/contact.html

I've told you how to do it, try reading my previous reply.

Are you using the link I gave you ?
