donations from serbia

hello,
i've recently joined the server and quickly came to a realization that it will be impossible for me to play during my free time cause the queue on icecrown realm takes 6+ hours.
donating wouldnt be an issue for me, im ok with paying, but for some reason my card has been declined. i've read on the forums that donations from serbia have been blocked for some reason.
now, i did some digging around, and found out that its possible to go around this blockade by using vpns and stuff like that, but i unfortunately dont know anything about that, so my question is basically, could someone explain to me how can i donate from my country and be able to avoid this darned queue?
thanks in advance.
