I'm assuming that the friend is using a different ISP also... So it would look like there's something awry with your account...
I will ask our devs to help.
Thank you for the GIF, by the way - that's pretty awesome of you. :)

Hm, the problem looks the same in the logs, so I'm assuming that the cause is similar to montcer's... <investigating intensifies>

Please let me know exactly what happens when you try to open a support ticket. What kind of error is being displayed?

OK, our friendly neighborhood devs have found the cause of the issue. Apparently a piece of code gets looped for purchases made from a handful of countries - Venezuela included. I should have noticed that myself, now I feel bad. :<

Anyway, a fix for this is in the works, and will be implemented as soon as possible. Sorry about the trouble in the meantime, though. :( Sadly, it doesn't look like using a card would work as a workaround.
