A New York judge concluded Tuesday that Dell Inc. engaged in repeated false and deceptive advertising of its promotional credit financing and warranties.

State Supreme Court Justice Joseph Teresi ordered the computer retailer to more clearly disclose that most customers don’t qualify for free financing or get “next day” repair service.

“It appears likely that there are many more New York consumers who are entitled to restitution who are not included in the complaints,” Teresi wrote.

New York Attorney General Andrew Cuomo sued Dell last year. Teresi gave him until Dec. 1 to identify all consumer claims for third-party repairs, new computers or higher interest payments than they would have paid otherwise.

“For too long at Dell the promise of customer service was a bait and switch that left thousands of people paying for essentially no service at all,” Cuomo said. “This decision sends an important message that all corporations will be held accountable for the promises they make to consumers.”
