Best network for Interstitial ads?
 

Hi guys!
Been awhile since I've been on here.
Redirecting focus towards the android marketplace with our first game release currently in beta.
However it's been quite a challenge finding the right network for ads.
We prefer fullscreen interstitial ads and I've personally found a number of other forums and reviews of people praising MobVista but I'm seriously starting to think they're all fake and paid.
After reading numerous people claiming they have great customer service I'm starting to think it's BS. I emailed them 3 days ago and reached out to 2 of the employees via skype about an SDK issue and have had zero response.
So now I'm thinking maybe I need to redirect my focus to another company.
I'd really like to get some feedback on what people have been using and prefer.
Thanks!

Mobilecore is a revenue-saver. I almost tripled my apps income by implementing their SDK.
