I read your question but I don't know anything about out-of-country purchase options as I reside in the United States. You can speak with an EA representative faster if you do a live chat with them, though I understand there may be a long wait time due to the issues with SimCity.
You can find the support link here:

Just enter a description of the problem and click the "live chat" link at the bottom of the page.
If they are unable to accept the payment option you are trying to use, they may be able to suggest an alternative method.
