Someone stole my video! Please help!

I’m asking you for help!

Someone reuploaded my dance@live that i edited together WITHOUT crediting me OR the original uploader.
Even tho it’s mentioned in the description.

Please, help me delete this video or at least make credit where it’s due!
Flag the video, spam it with comments about it, spam the user with msgs… anything.
Please!
