******* from car track

i have recently had a bad experience with car track and they continue to harass me with phone calls till this day ,when i want to cancel. I bought this car as a second hand ,then i called car track to get a unit in November 2025.I was told this car already has an active unit and all i need to do ,is to call the previous owner to do the change of ownership. I gladly did that process and the profile was changed to my names. Early this year i got concerned as i had never been able to track the car on my phone via the car track app.I then called in about the issue and i was told the unit is faulty and they will send technicians to come fix the unit.

Technicians did come to my house to work on the unit and they discovered that there was no unit ,and they sent a report to the office .What baffles me is that ,when i took up this profile i was sent a tracker certificate and i am wondering how was it assigned if there is no unit in my car as per the technicians report.

So i am requesting a cancellation ,as i have never got any apology or explanation from you guys regarding this debacle as they had been deducting money from my account for something i do not have. All they do is is ask for payments but they have never called to resolve the matter. So i am no longer interested in their services .All i get is: your situation has been escalated but nothing has been done. please assist.
