Scam company 
I upgraded from the R99 tracker to the R140 via miway. my battery was being drained and needed to be jump started almost every other day. 
It was a new battery and I had to go back where I bought it as I was sure that it had a problem. But only to find out after going up and down that the old tracker was never disconnected and was the reason my battery was being drained.
Car track now wants to charge me R600 for coming to disconnect that old tracker, something they should have done when Installing the new one.
Now no one wants to take my calls when I ask to speak to a manager, they just put me on hold for long, then drop my call.
This is a scam as they are responsible for this mess but want me to pay for they mistakes. 
Their customer service sucks but they are good at reminding you of a missed payment ??
