Painfully Poor Customer Service Support

The service and support from CARTRACK has degraded to non-existence. I have been struggling to do a deinstall and reinstall from one vehicle to another for two months now. Technicians come to site but then they leave because jobcards dont match job scope. Customer service and scheduling are not taking notes and never manage customer expectations. Money deducted for the service yet nothing was done. I requested to be released from their contracts because they are really not willing to provide adequate support.
