Netstar cancelation issues

I phoned in to Netstar to have my subscription canceled, the lady first tried using playing on emotions track ticks to get me not to cancel. The last time I called them about the unit because it could not working they wanted me to pay in and it would be a new kind of unit so a new contract for 3 years. The unit I have now is out of contract (over 3 years) why must i pay to cancel my subscription if we are out of contract? It's not the first time I have come across there bulling tactics and I think this should be challenged with the consumer protector if this is how they going to work with me.
