I have just bought Destiny the collection on PS4, which has the normal destiny game on disc & The Dark Below, House of Wolves, The Taken King & Rise of Iron in a download code, it also has a code for the Iron Gjallarhorn, this code worked fine but when I enter the one for the expansions DLC it says it’s already been used, how does this get resolved? I’m not forking over more money to get them individually when I should have them already.
