I got a reply and the Moderator said:
Thank you for contacting us.
Looking over your purchase attempts, I see that they are coming from a location other than the billing information you entered. Where are you currently located? How long will you be there?
I look forward to your reply."
So, try to restrict your authorized locations in account settings to 1 ip only but since got the error they need to unlock it once you prove them you try to pay from the country you say you are from
i think this is the problem
