Comcast has been ordered to pay $700,000 as part of a settlement with the state of Massachusetts.

Attorney General Maura Healey's office accused the company of deceptive advertising involving the prices and terms of long-term contracts.

Comcast will refund and cancel debts for more than 20,000 customers.

The assurance of discontinuance, filed in Suffolk Superior Court, settles allegations that Comcast failed to adequately disclose the actual monthly price and terms of its long-term contracts for cable services, including failing to disclose to customers that the company could increase the price of certain monthly fees at any point during the long-term contracts.

“Today’s settlement with the Massachusetts Attorney General’s Office reflects our ongoing effort to improve the customer experience," Comcast said in a statement. "While we disagree with the allegations in the Assurance –- which relate to years-old advertisements and do not reflect Comcast’s current policies and practices –- we are committed to partnering with Attorney General Healey and others who share our commitment to improving the experience of our customers in all respects.”

Comcast is the parent company of NBC10 Boston, necn and Telemundo Boston.
