ITunes songs not crossing borders

So I get the whole export restriction thing on the iTunes music store and blah blah blah, but when I switched I lost access to songs that are ABSOLUTELY in both the US and NL/EU store (I have numerous examples that I could rebuy from iTunes EU - same song, artist, album, everything). Anyone know how to report this to apple to get my purchases made available - none of the support options seem to line up?
