I need to add a VISA as a payment method to buy points and renew my subscription (im on chile region if the title it's unclear), i fill the data required exactly as i do in every other web site (amazon, google checkout, etc) and keep saying that the "the card number it's invalid" it appear on red letters under the card number, i tried 3 different international VISA and all the same, then i tried a Mastercard and there you go, ok at the first try...
You may say, then stay woth the mastercard, but i cant use that specific mastercard to purchase, only the VISAs cards... Please help, i read similar post on the web, im not the only one with this issue
