[wireless]

Over Year after moved recieved bill saying owed about 200.00 for cancelling tv and internet. Returned hardware. .was sure had credit on account because you actually pay ahead of use. Place moved to was included. Now movkng again and this "improper notice" never would have agreed to pay Telus 200.00 to stop their service after 3 years..ccts..any help on better no term contract for tv and Internet?
