Track released without permission

My Question or Issue

Hello! I don't know where to contact with this question, so I am writing here and hope that somebody would help me. Recently I found out that there's a track released by me and some random guy (collaboration). The thing is that he downloaded, completed my project from youtube and released it as a collaboration on all digital stores without my permission. I don't even know him. How do I take this down?

Project of mine: https://www.youtube.com/watch?v=-CoJ28i4eew uploaded this project only for learning purposes, not completing and releasing.
