Negligence and poor service

Tracker promised to send a technician to my place of reseidence to sort out my unit. An appointment was scheduled for the 7th of Jan, technician did not show up not make contact. I had to be the one who proactively follows up. I had to call in and request another appointment which was scheduled for today the 9th at 2pm. 2 hours later the technician has not showed up nor made contact. What I would like to know from tracker is if they cannot service me, charge for a service I do not have, why do they want to charge me a cancellation fee when I want to cancel the contract, seeing their are not fulfilling their end of the agreement? My vehicle has been without a working unit for over a month, which places it at risk, what should happen then should something happen to my car? Surely there are aware that it is an insurance requirement that I have a working tracking unit! Who is to be held responsible if I lose my car under any condition? Does tracker answer to an Ombudsman body? If so I would like to refer my case there because this negligence of theirs is of greater proportion than just dishonored appointments and horrible service!!!
