A while back I tried to log into my old account and found that it had the error code NP-2074-3.
I contacted support about the issue and they explained that someone had bought about $400 worth of the premium currency for fifa 2016 before rejecting the purchase on their credit card
I had never played any Fifa games before, so this was obviously an account breach made by a hacker, and I tried explaining this to the support assistant.
The reply I got was that regardless of how it happened, the only way my account was going to be unbanned was if I payed off the debt by adding funds to my PSN wallet.
I had heard of all these issues with the PSN servers having information stolen by hackers and the wanings about changing your password every time this occued so I did just that every time thinking things would be fine and I could go about my buisness but apparently I was wrong.
Obviously I'm not going to pay for someone else's screw up so I guess things are going to stay at a standstill for now.
