A grossely violated client of Tracker warning many

I had my new vehicle fitted with a tracking unit by Tracker in 2013. Have paid them since then until 2014 March. I decided to discontinue paying after experiencing/being denied a promised service and of which I am paying for. One particular evening I needed their service and the told me to wait as they have sent someone but I waited infinitely and no one came to afford me no help. I had to make other arrangements and pay another person to assist me whilst i am paying Tracker to come to my rescue. The next day when I called again to complain they told me they apologise and promised to send someone to come and have a look at the panic Button because it was dysfunctional but they have never sent anyone. Then I requested termination of the contract which they refused and demanded I pay for the outstanding amounts in terms of the contract. I refused but they continued deducting from my bank account. I had to keep on reversing these deductions every month and they would not stop taking money for a service i was not enjoying. In Nov 2014 my vehicle was ****** and they refused to track it until today I am without my Toyota Hilux Raider because Tracker does business in a *****ed manner.
