L'union des consommateurs and Vidéotron ltée customer Fernand Savoy have instigated a class action lawsuit against the Montreal service provider for capping the amount of data clients are allowed to download through the Extreme High-Speed Internet service. According to a press release, Savoy and the Quebec consumers-rights group argue that the cap conflicts with Vidéotron's claim online that the Extreme service is unlimited. They also argue that unlimited downloading was one of the reasons many people signed up for the service in the first place. The suit seeks a refund for over-limit charges. Earlier this month Vidéotron announced that it would limit downloads to 100 GB per month starting October 1. Downloads over that limit will cost $1.50 per GB.
