Thank you for contacting Sony Online Entertainment Customer Service department. My name is [his name] and I am pleased to assist you with your problem. After reviewing your email, I understand your issue to be trying to renew your account.
When you are setting up the billing information you are going to want to put your Country as Zimbabwe and then re enter your State. This sounds odd but this will take care of that problem you are having.
I do so love Sony's online credit card verification system. *slaps forehead*
In other news, I've decided to break down and renew my EQ account and start playing again, if you hadn't already guessed. ;)
