Tracker bad my man bad

I have fitted a tracker to my Land cruiser maybe 5 years back. On installation i was not allowed to witness installation no problem, from that date my tracker has never ever worked i have had so many irritating phone calls my car is moving etc. i eventually like today made a decision to tell them vehicle is ******. I have done it in the past ass well. For the past 2-3 years i have had numerous irritating phone call from *********** staff on alert my vehicle is moving or unauthorized signal or something, shame here comes the crunch ... i cancelled and stopped paying my tracker 2-3 years back. yes no payments every phone call after that i tried to explain to in competent staff the story, they waist my time fix the data until the next phone call. today i told them my car must be ****** .. please hold they ask me they are transferring me to MCC then i must hold for 3-4 minutes and the person answering ask me to hold again. It is a joke my tracker has never ever worked i crossed the border no alarm... i took out the batteries out to disarm it one night and after 1 hour i got and SMS if you ok answer \y"if not \""N' i answered \""N\"" it did not help. Hope the car and cell gets ******"""
