A Calabasas company named Cost/Benefit Corp., which was hired by the city of Los Angeles to audit cell phone bills, claims Los Angeles Mayor Eric Garcetti and City Attorney Mike Feuer failed to take action after finding out the city was overcharged by about $12 million and could recover as much as $39 million from its phone providers, the Los Angeles Times reports. Instead, the company claims it has not been paid, so it is suing the city. The city intends to countersue.
