I had to buy the game used since I can't get a hold of a new copy anywhere in my area. The online code was used, so I am unable to play multiplayer. When I try to purchase one in game, it says there aren't any. Any idea when I'll actually be able to buy an online pass? Sorry if this has been mentioned somewhere. I looked and did not see an answer, even with the search function.
The rep said he was looking into the problem for me and to hang on. Few minutes later, the chat window disconnected me because the chat was "inactive". Now I try to go back and it says customer service is closed. What a joke. Guess I'll try tomorrow.
Try to use the online store from PC and see if it shows up there. The PSN store on PS3 is horrible. Only use it when I really have to. Otherwise I just queue my downloads on PC and it automatically downloads to the PS3 later.
EDIT: I just checked it on the EU Store and its available as The Last of Us™ Network Pass. Don't know about the NA store though.
