Shaw Cabel Tricking Seniors into contracts

Shaw cable has recently tricked my father who is over 70 into a contract over some HD tv boxes. My dad made the switch to telus and saving 160$ per month. Now they send him a bill wanted him to pay the HD box, but they don't want to give him the HD box, and have taking him to collections. My dad has been a shaw customer for over 35 years, and shaw has never had contracts in that time. I'm going to switch to telus after all this... This is some pretty shady business practices.
