I've been trying for the last two days to get train tickets using the Renfe site. I am trying to use a capital one mastercard. I've contacted Cap one 4 times now and they insist Renfe hasn't even tried to put through a transaction. Yesterday I was given the G001 error message however today I got to the select a seat page and then got the error message.
Has anyone had luck using this card or should I try another one?
