First he has agreed that he will submit 5 articles daily. Later he said that he cannot submit them daily. He was very polite and asked to either self-mediate it or let him continue working. I needed these articles and I didn't have time to look for another worker for this project, so I had to agree that he will submit articles before the deadline but without submitting them daily (as was initially specified in the project). Finally he has submitted the large amount of articles in the last 2 or 3 days before the deadline. Surely I needed some time to check the work, and I told him about this. He answered "Sure, thank you for letting me know about that, contact me in the case of any problems" and... placed the project into arbitration, saying that I don't want to pay for his work. That was really frustrating, I will never work with him again.
