I paid him 90% of the project completion money, and he is always asking to keep creating milestone. He initially said the project will be done in 1 week, and he extended to more than a month, and till now its not completed. Extremely frustrating. I did my best to be as nice as i could. Anyways stay away from this freelancer.
