Freelancer — freelancer milestone payment

Address:	Gurgaon, Haryana, 122001
Website:	www.freelancer.in

I am working as a freelancer for two year. Now i found a big fault in freelancer website. I was awarded a project of 250$. The employer has released the first milestone of 250$. I have submitted his project to the employer. But within 3 hours the milestone is reverse back to employer. When i complained about it they said that the employer voilet our term am conditions that why the amount is reverse back. So please careful about it.
