Car track must stop calling me and going into my account

If o could give you 0 stars I would because you guys are terrible. One of your employers confirmed that my unit was not working in February after the suspicion because my car went in for repair and did not trigger the tracker( engine work) Battery died while at it.

She then said she will send a technician but advised that the car is in for repair I will call them when it's back- debit order did not stop mind you with the unit that's not working. April I called them to cancel the contract because it's upsetting to find that I'm paying for the unit that's not working- they continued debiting me till September and I reversed it. October 1st one of their agent called to say there's an outstanding balance. I told her the contract is cancelled and the reason she said she will then do immediate cancellation. Since then everyday at least 10 times they are calling me about that amount.

You guys just debited my account again even tho I cancelled the contract. For the unit that is inactive. I wonder how many of of your clients are driving around with an inactive unit yet being debited for it. I asked for a recording for the last call I had with your employee confirming that the contract will be terminated with immediate effect since I've asked for termination since April.
