I am trying to buy a couple of games, when i try add funds using credit card i get a "funds could not be added (56)" and i cant buy an online game code cause they are only sold to US customers on Amazon.
1) Hello and welcome to the forums.
2) As mentioned, this forum is for PlayStation Home support.
3) Moderation will very likely move this to PlayStation®Network Support.
4) Are you using a non-U.S. credit card. That's probably your problem. You may want to contact Amazon for assistance.
5) Don't be a stranger here. Be sure to check on the status of your query and maybe participate in many of the discussions on the PlayStation forums.
6) Good luck.
