AT&T might be suing Verizon over its “There’s a map for that campaign,” but AT&T is also on the legal defensive – although on a smaller scale.

A Chicago man wants to be reimbursed of more than a year’s worth of “hidden charges” of $5 per month. He filed a class-action lawsuit to get his money back, and more.

Jeffrey Hickel, who is a Chicago-area accountant, says he didn’t notice the extra charge for a 411-type service until he’d been with AT&T for more than a year. Although he was able to get it removed from future bills, he decided to take the phone giant to court after trying and failing to get reimbursed through phone calls to the company.

The suit is being filed as a violation of the Truth-in-Billing Act and the Illinois Public Utilities Act, in addition to breach of contract and a handful of other claims.

For his trouble, Hickel now wants more than just reimbursement. The lawsuit asks for an unnamed financial amount plus legal fees.
