Customer Service....none

The effort and lack of customer service. I thought there was an issue with the tracker draining my battery. So I called (took about 3 calls) to organize for a technician to come out. I was then told that if they come out and the issue is not the tracker, I'll be charged R600. I called Thursday 5pm to cancel the technician for Friday. The lady told me the email to her supervisor would cancel the request. Despite that, I received a message to say the technician would be coming. I called back on Friday morning to again cancel. The lady I spoke to was rather rude. I was told that it was cancelled. To then be called by the technician to confirm my address. Clearly he didn't get the message and Cartrack doesnt have a system
