Comcast recently climbed leaps and bounds in U.S. customer-satisfaction ratings due in large part to its decision to use Twitter to calm disgruntled subscribers, Bloomberg reports, citing the American Customer Satisfaction Index.

Comcast's ranking rose 9 percent during the first quarter, marking the largest gain among cable and satellite providers. The cable giant has undergone a customer-service transformation of late after it tied for worst place in the index in three of the past six years.

Comcast employs 10 people to monitor Twitter and find customers who mention service complaints so they can attempt to resolve their issues with the company.
