Cartrack charging,without providing a service.

Cartrack has been billing me,but the details on the contract does not reflect me,further more i don't even have a car anymore,so as per the "consumer protection act" how do they bill me without providing me with a service. So if the contract details is incorrect,this should render the contract null and void!!!!!!!!!!!! Please help Hello Peter. It seem unfair tat the rich is getting richer,and the poor getting poorer.
