Okay so today i bought fifa12 at EB Games for whatever pre owned and i went to put the online code in and obviously didnt work because someone has already used it.. what do i do to get another one or how can i access online? cheers

Bring it back and tell them.....

if i call them are the able to give me a code over the phone or something?

It's pre-owned it means the code was used and you have to purchase a new code or something like that same as BF3

-_- ....... Its how EA make money off pre owned games. Go on to the game and they should be somewhere saying purchase online code if not just search for it on the PS store.
