Cartrack - Zero service

my new vehicle came fitted with a cartrack system first it was impossible to log onto the Cartrack app to track the vehicle once that got sorted we noticed that the tracking didn't respond and it would be days behind actual activity. 8 phone calls later and numerous e-mails the system still doesn't work. Not one e-mail to client services were answered .Every person you speak to transfers you to the next person. They even ask you to rate their service but the option wasn't available at the end of the call - CANCEL CANCEL CANCEL
