I can understand that they ain't gonna fork cash over to buy it back, i mean, they have no sort of guarantee that the hackers who stole the info in the first place doesn't just have a copy of it, so buying it back would most likely be useless.
This should really, REALLY make companys stop storing your credit card info unless really needed, and preferably store it offline if possible.
I don't think i've ever used my credit carn on PSN, and i know for sure it won't ever happen, they can go fuck themselves, and learn to deal with confident information in hope of winning their costumers trust back.
