State regulators issued a final decision today ordering Connecticut Natural Gas Corporation" href="/topic/economy-business-finance/connecticut-natural-gas-corporation-ORCRP003790.topic">Connecticut Natural Gas Co. to retrain its customer service representatives and donate $150,000 to fuel assistance programs following complaints that it underbilled about 3,400 customers and tried to make up for the mistake by charging them hundreds of dollars extra on monthly bills.

The state Department of Public Utility Control also reiterated its earlier ruling that the company will have to collect the amount of the underbilling over at least 12 months without late fees or penalties. Some customers owe more than $1,000, billed to them in January and February, after four rogue meter readers fabricated readings in the previous two months.

The meter readers have been fired.

State Attorney General Richard Blumenthal" href="/topic/politics/richard-blumenthal-hpp4069.topic">Richard Blumenthal and Consumer Counsel Mary Healey criticized the DPUC's decision today, saying it doesn't go far enough.

"DPUC should have severely fined CNG instead of slapping its wrist," Blumenthal said. "The cost to the company -- $150,000, more than one third of which it can write off its taxes -- is laughable."

Healey said that she was "dissatisfied" with today's decision and called for at least $300,000 in compensation from the company for customers who received high catch-up bills.

"The consequences for CNG in the decision do not go far enough," she said. "The DPUC has a duty to balance the interests of the utility and the utility customers, and that balance clearly was not achieved in this case."
