It sounds like you bought the season pass and then downloaded the DLC from the PS3's marketplace. Once the season pass has been bought and downloaded, you download the DLC through the in-game store. You might be able to get a refund if you contact customer support (for the PS3) and explain what happened.
Hope this helps.
I tought i did, back to beginning, contacted Sony, told me to Delete Ps store and if it wont work, i need to Download remotely from Pc. Wanna have a guess did any of that work? Nope, i also cleared game cache and tried again, but nope D:
