No sense of customer service and Urgency

The product was installed into my vehicle and totally gave a wrong location. A second device was installed and still was not accurate. After many phone calls and struggling to get hold of them the account was cancelled. I am now struggling more that 2 days for the planner to make an appointment to remove the device from my vehicle. The service is really pathetic and they have no sense of URGENCY. I just want the device removed so I can get another tracking company to install but they just don't get back to me !!!! How can they recover your vehicle if it shows about 50 km from where the vehicle actually is.
