This company was fined US$7.4 million in 2014 by the The Federal Communications Commission (FCC) for using personal cellular data to market to customers without their consent. Verizon is accused of collecting detailed information about a customer's calling habits, like how many calls they made, what services they subscribe to, what numbers they dialed, and their geographic location whenever they placed a call. According to the FCC, Verizon "failed to generate the required opt-out notices" as early as 2006, making 2 million of its customers unknowing participants in the carrier's marketing plans. That data was then used to market Verizon's services to new customers.
