Trouble With Distribution

So I was checking out my artist profile on Spotify and was surprised to see a song on there which I didn't create. Someone had put up a song but it fell under my artist account. I contacted Spotify to fix the issue but realized that it was bigger than I initially thought. The song is also on my Apple Music account and I'm assuming even more platforms. The artist who uploaded this is putting up another song under my profile as I was indicated by my email telling me to excited for my new Spotify release. Do you guys have any suggestions for how to go about this? I don't want to have to contact every platform individually. Thanks.
