As TAA says, you need to ask paypal why it doesnt have your country in its list. We are simply not able to accept Credit or Visa transactions, that is a choice that 500servers has made. It can be very expensive, and basically, not worth it for the small amount of clients who cannot use paypal.
That does exclude some, and as much as we would like to provide you with a service, sometimes, we cannot.
I suggest that you try some of the other hosting services out there, google will help you find them. Also, its christmas day, I wouldn't expect a reply from Franky500 for a few days, he should be taking some well deserved time away from the screen.
Unless you are paying for a year in advance, or a lot of servers on a regular basis, I think it is unlikely that you will be able to pay via bank transfer. Why not find a team member, or a friend in a country that paypal does support and ask them to pay for you, much easier all around.
Incidently, our payment methods are stated on our website, billing system and company forums.
Merry Christmas!
