Sorry for the bump, but I'd like to add some info, if that's okay.
I recently discovered(personally) an indirect method of purchase for people with limited access to the current methods.
SEA users will be familiar with MOL points.
You can use Molpoints to buy UGC or PaySafeCard(credit?) easily.
I haven't quite tested it, yet, though. (the options are there and it seems legitimate)
If this post is irrelevant and pointless, please notify me so I can delete it.
