I cant play online on ps3, error playstation store/ game card

Hello, I bought Mass Effect 3 on the PS3 PlayStation Store, I downloaded and installed the game on my console but when I go to tells me that you need an online pass to activate the online features of this title
I'm used to (I have the madden12, 13, battlefield and other evidence of your computer) when I buy the "full game" biene with online pass.
however, this time, apparently it is not, but when I wanted to buy it, I realized that the online pass is not in stock options (the comrpar the full game, the online pass disappeared), so I I have been contacted by phone playstation network, and they analyzed serca half hour my account and I replied that I get in touch with you, then the game would have some error and should be compensated with the code online.
They gave me this number to locate them, however,
6281001 18664195766 or this one and the next number is 506500
my psn account is (edit: email removed for security reasons) and my online id is franciscolaris
waiting for an answer or some help and I would not mind buying the online pass but not on my mind because of a possible error I get at your disposal in the same mail account
(edit: email removed for security reasons)
Greetings and thanks for sharing the magic of electronic arts in every game.
a humble but faithful follower.
