CARTRACK THE MOST USELESS TRACKING COMPANY

The most useless tracking company i have ever come across in my entire life. First of all they were unable to recover my vehicle when it was hijacked, telling me how much they can not get signal of my tracking unit, the service was also bad and they did not have my details in their system, i had to give them my ID number over and over again to retrieve my account which took them long, now this questions their systems. Fortunately my other tracker recovered my vehicle within an hour, 6 hours later Car track team arrived at the scene because they got information from the police that my vehicle was recovered. I do not understand why they came because we were done at the scene and my car was taken to police pound. Now today Cartrack has the nerve to tell me that i should continue paying for their useless service and that their contract binds me, i mean what am i paying for ? Their useless unit and bad service ? I need my contract cancelled asap and the lady called Nompumelelo is telling me to pay R1700 cancellation fee for what when i did not even reap anything from their bad customer service and useless device. She told according to their system they are the ones who recovered my vehicle and that is absolutely nonsense. I am not going to pay for any cent!!!!!
