How can I cancel my Optik TV?

I am beyond frustrated right now.  I have been a loyal customer with Telus for 26 years and have just recently decided to cancel my OPTIK TV.  I have internet service at both my primary residence and my cabin and have decided that I no longer watch enough TV to justify the cost.  I phoned today, with my account number, my PIN and all the information needed, my name is on the account but I am not the ‘primary account holder’ - that is my husband.  Even though I pay all the bills and manage this account I am NOT ALLOWED to cancel this service!  I can add all the services I want and rack up the bill to a bejillion dollars without my husband - what the hell kind of racket is this?  I am pretty tempted to phone up BELL or ROGERS and see what they go going on.
