Unfair and incorrect hand-over, accompanied by poor service from Tracker

I cancelled my tracker account as I gave the car to my nephew and later decided to sell it. I cancelled it early last year if not in 2021, to my surprise Tracker decided to hand me over this month. i even called them and I was assured that it will be cancelled and they even stopped debiting me. Dealing with Tracker has been nothing but a nightmare. Their service is terrible they have this "Don't care attitude".
