ME3 Multiplayer on Ps3 corrupted?

Logging into multiplayer yesterday I noticed I had several new character kits open that I never had before. I checked out my weapons and had several less than before. In tried to play a game and got disconnected after 2 minutes. I tried again a few times and no game I joined or hosted lasted more than about 2 minutes.

Is my mp online data corrupted somewhere along the line or has it Ben hacked or something else?

Please help.
