SWTOR Payment Error

Hi guys, I got problem here, I've been trying to get my self to be preferred status player and buying it for 19.99, but as I proceed to pay it turns out to be a General Error and told me to try again later, I've keep trying for about 4 times a day but it still like that, I cant contact the customer service cuz I'm not in any UK,US,Germany or France Region, and my country isn't listed in the contact list either

Can anybody help me?
