I joined car track in March for my 2 vehicles and end of March I paid my correct monthly bill of R504 .now end of April was billed 804 because they re activate the car I once registered with them and the car was registered with 159 tracker with no camera now my kia is being charged 259 without my authorization and Kia doesn't even have a tracker . How do I pay something that I didn't authorize how do I pay something that I don't have .they have been taking me from pillar to post now was told I'm liable to pay cancelation fee on Kia the one that tracker was canceled 2021 . Tell me how possible is that . All I want is to pay wat I signed for . I'm not happy with car track they really messing up my life to be honest . Can someone deal this and give me solutions. ***
