yup, my company worked with them too, they never paid us, they admitted they owe us, we've written them on every social network possible and never got response or money
seriously, these AdMedia guys have fooled so many people! I had also recently an experience with Guru Lahore (his nick sometimes is blackb), my company paid him quite big amount of money, he sent us all fake traffic and after our complaints and attempts to solve the situation, he just stopped responding all together
yes, we also confirm that AdMedia owes us quite a sum of money and never paid it back, just started ignoring us, ever responded to any of our messages, all attempt to negotiate and find a solution were futile
Time ago, I think they are legit company... but now, too much complaint about their payment for publisher.
