Shocking service from Cartrack!!!!

I traded in my old car and have a new one. I contacted cartrack on 19 April and asked them to remove the unit from my old car and install in the new one. I was told there was a fee of R800 odd which I agreed to. I ask them to please remove the unit from the car before it got sold and a week went by without anything done and the car was sold. I'm made numerous calls, waiting on the call endlessly to be transferred to this department and that. I spoke to the manager at the Durban branch 6 days ago she assured me that they would come fit it the day after and still nothing. My insurance company keeps reminding me that I'm not covered for theft and hijacking until I send them the tracker certification. I don't have the R2000 odd cancelation fee that cartrack asks for otherwise I would have canceled and changed my tracking company.
