OC Ca$h payment issue

[Guile]

Hi everyone,
I've been occasionally promoting oc cash since the beginning and gathered some money there. I received only one and only payment for some low amount of money while I was having much more at that time. Today, they owe me over 500 USD. I contacted Chris Stewart, who seems to be at least managing their site, he replied he will investigate this matter with accounting. Unfortunately, it was his last reply which was sent to me in the middle of December. I then tried to contact him again via ICQ and someone at support but with no luck so far

Maybe I made a mistake waiting patiently for the payment to be made without letting them now that something is wrong earlier. Anyway, they should at least return my emails rather then keep me in uncertainty.
I'm far from saying "beware of oc cash" but I can't also say that this thing doesn't irritate me a little :/
Can someone perhaps give me a hint about how can I possibly accelerate this matter or what to do next? I would really appreciate it.
Perhaps Jay would give me a helping hand on this..
