As a customer who has had Cogent inflicted on us (when Verio sold all their domestic internet lines to Cogent), we've had nothing but pain and bumbling inefficiency from them for the last six months.

I contacted Cogent's "premium" help desk last night when I found that I was suddenly no longer able to get to our networks in Australia. The tech had no idea that his own company was in the middle of a huge peering battle with L3. I had to tell them!
