Ok, So i tried to renew my Sub with credit card.. Didn't work. I have brought things with it recently online and details are the same as it use to be, SO why wont it work

So then I turned to my usual method of any online gaming credit which is the GAME CARD. but guess what?

There are none in New Zealand right now. at all. the store which I brought the game from doesn't have it and I am slowly dieing from the lack of FF:ARR game time
If there is please direct me to one, because I have been to EB and found nothing.

Please Why are there no game cards here? Why wont my Online payments work because of error 601 and when will I be able to play again. because soon I wont have time to play and right now the only thing keeping me from going nuts (due to the uncontainable excitement and love for this game) is watching guides on how later I might be able to get pass Coil and so on.
Please SE help meh...
