itunes account disabled

Try going to https://appleid.apple.com and change your Apple ID password.

If that still doesn't work you will need to call Apple on the phones directly to find out why your iTunes account has been disabled. Usually this would be because some type of fraud was detected and disabling the account protects you. So it's a good thing, but does put it on you to get a hold of Apple.

When I buy coins for my game I found my account is disabled
