Missing iTunes Content

Ok, so I don't where else to put this: earlier this morning I used a card to download the "complete" Beethoven Piano Sonatas..as in all 32 of them. However once I got to listening to them, I noticed 2 of the collection are missing; nos #19 and #20 to be exact.



Who I contact about this? I paid for all 32.. not 30 of them!
