I read the great guide that's posted on TripAdvisor, but I'm still not having any luck purchasing Renfe tickets online. I've tried using both a Visa and a Mastercard- neither will work. (both have been cleared for international purchases). I get the G001 error message. When I called my credit card companies, both companies told me that they can't even see any attempts being made by Renfe to charge the card.
I'm trying to purchase 2 one way tickets from Madrid to Avila on Nov 22, then Segovia to Madrid on the same day (we're going to take a bus from Avila to Segovia mid day). I'm also trying to purchase 2 roundtrip Madrid-Toledo tickets for Nov 23.
A rep from Mastercard called the International number for Renfe and was told that tickets cannot be purchased over the phone. I'm not arriving to Madrid until Nov 21. I really wanted to purchase my train tickets ahead of time because I know the trains sell out in advance. I'm nervous now. Help!Edited: 02 November 2011, 18:19
