due to their constant refusing to pay, I have indeed found out that their system is very poor. anyone can easily scam them and go unnoticed for a very long time. this again resembles mtgox.
So you did try to defraud them, they caught it, and refuse to pay you out. Sounds reasonable on their end.
lol.... no.
after i found out their huge flaw, i am even more concerned as to why they are avoiding payment. they are probably running out of funds like mtgox.
