Hi, i hope i posted in the right section.

I have won a project a few weeks ago, the employer was okay, payed the milestones when he should, he had good reviews and so on, i delivered the files, the project was closed, the final payment was received, reviews exchanged and everything was okay.
Today i log in to freelancer and i discover that the project is opened again, and the entire sum i have been payed for MY WORK has been taken back by freelancer due to some.... account problems on the employers side.
Can they do that?? after all i lost time to deliver the work, i have lost fee for winning the project, now i lost the money for the entire project, lost good review and rating (now i have delayed time on completing the project... cuz it was finished 2 weeks ago, and it's still active).
What can i do?? why did they take the money from my account if employer has problems?? Shouldn't have they verified him better?? it's not my freaking fault, why should i pay.... they screwed it up they pay.

Thank you,
