Useless Service.

I have 13 units with Cartrack yet I can not reach anyone to assist me. Useless service. Useless call centre. Technicians who fit the units do not know what they are doing. My one vehicle nearly burnt out due to electrical wiring shorts that melted all the insulation on a glowing red hot copper cable. The unit on another vehicle stopped working and when a tech finally came to attend to it, he could not even find where it was installed and said I needed to sign a new contract for a new unit to be installed. Now Im paying for 2 units for 1 vehicle. And they still charged me for the call out even though he couldnt find the old unit. Totally frustrating trying to deal with Cartrack. Emails are never answered and the call centre keep you on hold forever. VERY DISAPOINTED with their service
