Conservant media (valueclick media) team not responding... Any CPM alternative?

I've read some reviews about valueclick media aka conversant media.. I've registered but no reply from them. I also send them a message via their contact page, still no reply. Don't know if their team is active or not.

I've over 30k daily pageviews with up to 1million monthly PV on my tech blog with quality and unique tech and gadgets updates.. and I wish to monetize my site with their cpm network. Since there's is no response from them, can anyone suggest any better alternative?

Thanks in advance..

 

i think it's means then don't like your blog ,so you will not be allowed as their publishers ,that's all
