Cartrack don't go there

I have several vehicles with cartrack and sold one, submitted the documentation for change of ownership. I t has been a struggle to get he change of ownership done for about two months now. There just seems to be no urgency or accountability form Cartrack to get this done. I have been in contact with several staffers and I just don't have faith in their ability anymore. What scares me more, that if a remedial issue like this cannot be resolved within a acceptable time frame - what would happen in one of my cars is ****** or hijacked. I'm afraid of their service going forward. I am certain that recovery would not happen. I am going to raise this seriously and must be allowed out of our agreement so I can choose a company that can actually service my business. So frustrated.
