Worst Service Ever

Unfortunately I cannot give this sorry excuse for a company less than 1 star. We had a CarTrack unit installed in our old car which was taken as trade-in when buying a new car. CarTrack was informed and promised they'd remove the tracker from the old car, and install it in the new. OK, so far so good. CarTrack came to the dealership where our old car was and un-installed the tracking unit. That was a month ago! Since then nothing, well apart from taking money out of our account, and demanding money for switching the tracking unit to the new car. I have tried to call CarTrack multiple times, and the few times I have managed to not be cut off, I have been promised that someone will call and schedule installation. So far nothing! I am seriously considering taking them to court.
