i cant purchases on my game last empire war z need help please

Difficult to try and provide help when you don't give any information about the problem. What happens when you try to buy something ? If you are getting an error message then what does it say ?

If you are getting a message to contact iTunes Support then have you done so ? If not you will need to (these are user-to-user forums) :

- go to http://www.apple.com/support/itunes/ww

- click on your country's flag (the country where you are, and which is therefore the country on your account)

- click on Contact Support towards the top right

- click on Get Help under 'Talk To Us'

Or use this form : https://www.apple.com/emea/support/itunes/contact.html

If it's a different problem ... ?
