How can i contact support? (regarding the online shop 1751111 issue)

Hello guys

After reading several threads in this forum (and others as well), i had no choice but to contact visa and tell them to let me do the transaction.
They told me is already enabled to do it (i tried it but i still get the 1751111 error), but it seems the CC is still flagged.
So... the big question is, how do i contact support in order to get my card unflagged? I´m just looking for the address or something, that´s all.

Thanks in advance

Anyone? please

This is the URL you need to go to, that will direct you to the right place to submit a question/complaint/etc.:

http://www.guildwars.com/support/default.php

But I will warn you in advance, they will not be very helpful. When my credit card was turned down arbitrarily, they just told me to go away and come back in a week.
