Problems buying the license from Argentina

Good afternoon friends, I find myself in a problem, when I want to pay my license from the Sheetcam page with my card, it does not accept the payment. Is there someone in the forum who can advise me how to pay for the license from Argentina. I currently have black international credit cards, Master Card or Visa.

The email you supplied when you purchased your license did not work. I re-sent it to the email you used to register on this forum.
