Tracker faulty decline to repare

I am appaulled. I have never experienced such horrible service. I had the technician here at my work who refused to put the new tracker in as there is no garage to work in. I have been driving around for months with out an operational tracker. I am actually getting to the stage of where I want to cancel my contract. I cannot take time to go and take the car to your offices for the installation. I have been paying for nothing. What a waste of money. Now because I want to cancel the tracker, my insurance premiums will go up. THANKS FOR NOTHING AND WASTING MY TIME AND MONEY.
