The Arizona Attorney General's Office settled an $11 million lawsuit against CenturyLink for allegations of "deceptive and unfair advertising and billing practices," officials said Monday.

CenturyLink, a company that sells local and long-distance telephone services, internet services and television services, is accused of failing to apply up to $1.9 million in discounts to Arizona customers' accounts between 2013 and 2016.

The company is also required to pay the state $7 million and invest $2 million in "improvements to fiber-optic infrastructure in areas that the Attorney General's Office determines are in need," officials said in a news release.

"This settlement holds CenturyLink accountable to customers and will provide significant technological infrastructure investment for the state," Attorney General Mark Brnovich said in a statement.

Arizona customers were promised various "closer discounts" as an incentive to sign up for service, which they never received, officials said. The terms of the Arizona consent judgment would require CenturyLink to refund money to those customers.

Affected customers will receive a refund on their account varying from $20 to over $1,000 per customer, depending on the promised "closer discount."

CenturyLink will contact customers who no longer have active accounts to ensure compensation. Questions regarding refunds should be directed to CenturyLink.

The company is also accused of "failing to disclose or omitting terms and conditions applicable to consumer orders — such as early termination fees, improperly billing consumers for returned equipment and charging consumers after they canceled services."

Century Link allegedly failed to inform customers about an "internet cost recovery fee," or discretionary fee that effectively increased monthly bills for customers enrolled in the company's "price-lock" promotion.

The settlement will require the company to stop charging the internet cost recovery and early termination fees. CenturyLink must also fully disclose all applicable terms and conditions, send order confirmations within three business days and only charge customers the amount they've been quoted.
