During a Senate hearing on its proposed merger with Time Warner Cable, Comcast Executive Vice President David Cohen admitted that Comcast could do a better job on customer service.

"It bothers us we have so much trouble delivering high quality of service to customers on a regular basis," Cohen said. "Sometimes, we need a kick in the butt."

Cohen's comments came just a day after the Consumerist rated Comcast the worst company in America, beating out agricultural giant Monsanto by three percentage points.
