Cancelation nightmare

We as a school had the exact same experience as one of the previous complainants have regarding canceling our membership. After numerous phone calls, no agent could confirm the type of vehicle as well as the registration number of the vehicle that has been monitored and paid for. I was newly appointed as the principal and tried to establish which one of our vehicles was covered. This dragged until we stopped the debit order. Soon thereafter we received a notice that we were in arrears and should pay. We contacted them again and the agent answering our call still could not identify the vehicle under discussion.

How on earth could Cartrack protect our vehicle without having knowledge of this vehicle?

The account number is ***.

Can somebody explain please?
