I always find that I am paid right around the 30th of the month (my last payment, for instance, arrived on 9/30)...so, for my records at least, I am not due payment yet.
Whatever the case may be, wheather they pay on time or not, they are not really a paid survey site. They get surveys from survey panels, then send them out to you and they get a cut of every survey you take. Maybe they are getting paid late as well....
