Refusing to cancel my membership: Lack of Transparency

Cartrack is extremely poor in customer service,

I have been with Cartrack for over 3 years and I am no longer renting my unit but instead pay month to month. For the current month I had some financial issues, and I reversed my payment and no one from Cartrack had advised me that I obliged to pay every month, instead based on information I received from your agents when I joined, I was advised that once my unit paid off, I can choose to stop a payment and reinstate later as I was no longer renting the unit.

Now that I want to cancel, I am refused cancellation by the agent and they want to drive me from pillar to post. Why is it so difficult for one to cancel. The agent I spoke to tole me straight that he will not help me to cancel unless I pay (this is ******* to keep a person on a contract to which they no longer desire to stay).

I mean if I am paying in advance, and I do not need the service for a particular month, why should I be forced to pay.

Cartrack cannot treat client like this.
