Rev.com scam company

I’ve been doing transcription work for just a week for this company and received my first bad rating for a project after which they immediately closed my account. I think this is so unfair seeing that my ratings for all other work was high! I believe this company is a scam and should be reported and shut down for getting people to work for them for free then closing their accounts. I’m still supposed to receive a payment for the recent work I’ve just done, but I’m not sure if they will pay since they’ve closed my account?
