How do I file a complaint against a freelancer?

[#1]

I hired him but he cancelled the contract so I can't give feedback that way.

I need to complain for the following reasons:

1. He didn't do the work I asked of him,
2. He keeps giving excuses why he can't do the work,
3. He cancelled the contract without asking me,
4. He doesn't communicate to me when I have asked him to complete some work as to why it hasn't been done,
5. He asked that I hire and pay him off the Upwork platform,
6. He says he bought Instagram followers for an account I asked him to create when that was never part of the job description.

I need to make this complaint official to protect other potential hirers. I would also like the complaint to reflect on his profile.

I want to point out that I don't think he's a bad dude.  I just think he has a shocking work ethic (or at least not a work ethic that aligns with my own values).

I think you should talk to Upwork support about this.
