I sent the bill for a long time almost 1 month ago. But so far I have not received any payment. I have sent many emails to support but they did not respond. They made ??me wait so long. adnetwork.net are scammers! Stay away from this ad network.
I do not think you are the first one to complaint about not getting paid from adnetwork.net, there are many old posting in dp as well, a lot many other had the same experience with them
