How do i contact Adcenter?

I want to send them an email or get through to them via chat but I cant see anywhere on site where I can do that. The problem is my campaign is marked as eligible but there are no impressions at all. adCenter support chat always say its unavailable and there is only the online sales form option but I think thats for sales only. I do not want to phone them. Thanks

Seems system doesn't allow me to post url's.

Sent you a pm...hope it helps
