I've been Vending there for maybe a month, just since Apollon exited, and the Support Team is probably the most responsive of any of the Major Markets. I am on White House, and Empire, and the people at Dark are very easy to deal with and seemingly online 24/7. I think I have had close to 50 orders placed, some fall through before I get to fill them, but still that's pretty good.
