I performed work for them in June and have not been paid. When I call I get numerous excuses (programming issue, B of A merger with Wachovia, bad economy) as to why my funds have not been released. If you go to the forum below you'll see that there are quite a number of people who have not been paid for work. You already have this company on your 'suspect' list so here's another complaint.
