Got a project on their site. Was paid an advance. Was charged $150 for the job, started the job. The client suddenly charged back the amount. I complained as follows: I received this message from you: "We are writing to inform you that the payment you received for "xxxxxxxxxxxx"' has been reversed. We received a charge back from the payment gateway and in accordance with our terms and conditions we've reversed the funds. I suggest that you stop working on this project and contact the buyer to resolve the issue. "
I responded " Since no payment has been paid to me (rather, your website has wasted my time by putting me in touch with doubtful characters). I owe you no payment. Please reverse the 10% you were taking from me as a commission. I shall make payment only if I am paid."

They replied" Unfortunately, commission fees are no longer refundable once the project has already been awarded to a Provider. Please contact your Buyer regarding your reversed payment and please make sure to settle the negative balance of $150 within 35 days to avoid your account from getting suspended."
I think this is unfair and arbitrary. They protect themselves, but refuse to protect you. Why should I be charged for deficiency of services from their end? Can some one get me justice?
Mean while, beware of this site and avoid it.

I remember that i posted a project cleary said I need US programmer only to bid. I ended up having people from India and Pakistan bidding claming from US, but couldn't verified they from US
