"We receive complaints every day from consumers who have been fooled. They have clicked on an Internet ad believing that they have placed an order for a free trial package, when in reality they have signed up for a subscription, and money has been withdrawn from their credit card without their knowledge," says Henrik Örnstedt, an investigator at the consumer protection agency.

Facebook spokesperson Jan Fredriksson says that the social media site agrees with the request of the consumer agency.
"We want to remove bad forms of advertising because it is hurts both our users and Facebook," Fredriksson says.
Facebook has until Friday to inform the consumer agency about what measures they intend to take to solve the problem of misleading advertisements.
