Dear colleagues,
Never ever start having a deal with this establishment.
The mechanism they steal your money is quite simple:
1) you place your bid
2) you are awarded
3) in a couple of minutes your project is marked as "Incomplete" and you are to pay 10% of its cost (which you have never received).
You have neither rights nor place to appeal.
I am sorry for those people who had money on their accounts when these "incompleteness" happened. All their savings were simply stolen.
I was lucky enough to have 50 cents at the moment. Thus, I congratulated the fraudsters with the huge loot;)
Nevertheless, the time I had spent to build my profile was gone for nothing.
