Some Pinnacle Security customers said they were misled into signing up for contracts they didn't need or couldn't afford and the company charged a hefty early termination fee.
The allegations led to an investigation by police in suburban Dolton and a lawsuit was filed.
On Thursday Illinois Attorney General Lisa Madigan announced a deal that bans Pinnacle Security from deceptive tactics. Also, the company must return money to customers who signed contracts after a deceptive sales pitch.
Customers have until May 8 to request their money. Call the attorney general's office for more information.
