Cancellation of contract my foot!

I signed up with Car Track early this year, the tracking unit was installed. I found out the panic button wasn't installed. I called the contact center to lodge a complaint. I was then told that the panic button had an additional fee which I wasn't aware of. I requested a copy of the telecom conversation " the contract " . The contract was never sent. I decided to cancel the contract within the week. That was never acknowledged. I have gone my local Car Track in New Germany to have the unit removed. I was told it will not be removed yet I had requested to have the contract cancelled as per NCA with 7 days without any fees. I have debited. No one wants to process the paperwork. Ranta at the New Germany seems to be trying to assist me . For the past month I'm going back and forth with no assistance.
