Who do I contact about Itunes Match having the wrong song matched?

So... I'm listening to some music on my ipod. The song "Forget You" comes on, and instead of the version I used to have that says "forget you", the version that sayd "f... you" comes on. Now I never purchsed that particular version, so I checked to make sure I had the same song. It was still the same one I've always had, same cover. Then I deleted it from my iphone, and listened to it streaming, and the wrong version is playing. Does anyone know how to get this fixed?

thanks.
