Horrible service, no follow up.

I received a message 7 Jan 2020 that our unit is not working, and i have to phone to schedule a maintenance. I then followed up by calling Cartrack and informing them that maintenance is necessary. They told me somebody will phone back. So today "28 Jan 2020" i phoned again to follow up. The assistant confirmed the system read that my maintenance was pending and was so rude to me and shortly after i got cut off. I phoned again to follow up, and now i have been told that the maintenance dept is backed up. So if something was to happen to my car as this unit is a prerequisite to my insurance policy I would then personally hold Cartrack responsible for my losses. Horrible service. Not my negative rodeo with you guys either.
