Very Disappointed With Service Received.

I am extremely disappointed in Cartrack, I have had problems with my cars ignition since installation, I have been contacting them continuously for the last 3 weeks and just get told they will send someone out and still nothing. My car will not start now at all, I have spoken to Auto and General emergency services and they have told me its the ignition due to the Cartrack. They need to fix this urgently or just remove it.
