How can I use a Thai bank card to pay for tickets with Austrian Airlines?

Thanks everybody, i fixed the problem, it turned out the bank blocked some of the international airlines or some kind restriction on my card. Even i addressed this problem already in 4 different bank offices before and no one helped, today in the one of the bank offices another worker was understandable enough to take my phone and call the call center and explain everything and they said they "Activated my card" for other companies besides Asians. So if someone else have the same problem - just need to be pushing forward with different bank offices or different workers, dont trust if bank worker tells you cannot be done, try with another worker and can be. Specially if they are acting unsure which they almost always are.
