Frontier Communications will pay restitution of $750,000 and spend $10 million to upgrade its broadband network to settle an investigation by the Minnesota Attorney General's Office over customer-service problems.
Frontier has been under fire from Minnesota consumer and telecommunications watchdogs for the past couple of years after a deluge of complaints about its phone and internet service.
The Attorney General's Office was investigating possible deceptive market practices related to Frontier's internet services.
With the settlement announced Monday, Frontier agreed to fully disclose its prices for internet service to new customers and allow many current customers to cancel their service without penalty.
"For so many folks, especially in Greater Minnesota, affording your life means being able to rely on the promises your telecoms provider makes for the internet service you depend on," Minnesota Attorney General Keith Ellison said in a statement. "For too many Minnesotans, Frontier broke its promises."
In a statement, Frontier said it "is pleased to have this matter resolved."
Frontier, which also operates under the name Citizens Communications, is Minnesota's second-largest landline telephone provider with 90,000 customers, many in rural northeastern and southern parts of the state. Norwalk, Conn.-based Frontier also is a major internet provider.
The Minnesota Public Utilities Commission began looking into Frontier in 2018 after fielding a host of customer complaints. The PUC ordered an inquiry by the Minnesota Department of Commerce.
