Cannot donate, can't use gift cards either?

The only options for donation it gives me are Credit card (visa, mastercard etc.) and this thing called Mint. I do not get the option to use a subway,burger king, cvs gift card.... There is another guild mate of mine who is in California, USA as well but he is able to donate using the gift cards mentioned... it doesn't make sense to me.. is it my ISP? i guess i cannot donate to lordaeron/warmane then huh... guess im stuck waiting in queue on my DAY OFF FROM WORK... ........
