Solved
Oasis has always been great and very responsive for me, but there are also tons of other networks out there. Why not stick with the networks you are currently with?
Try to email them, I know there were some affiliate conferences now, maybe Darren was attending? I've been just ignored by one rep at a traffic source for like 5 days straight, who is usually VERY active ... turned out she was on a conference and I missed the info on her skype profile. Things like this can happen, but AMs usually are checking emails...
Thanks for your suggestion.
I will email him today
