There have been loads of complaints about these scammers, and they even tried to bombard this message board with fake "positive" reviews, but the administrator caught them and banned them from here. There have been attempts at enforcement against them.. you could also write to

They may not be able to help, but the more official complaints the more likely enforcement action can be taken. They should be shut down.
