The worst service imaginable

After switching my insurance cover, I contacted Cartrack on 16 July to upgrade my unit as it's a requirement. I was told that an email was sent to the insurance department who will phone me to make the necessary arrangements. Every time I enquire about this, another email is sent to this department that does not have a phone number as I sit with a car that is not working, losing money and not covered by insurance pending this installation, should anything happen to the car, I'll lose a lot of money. My next step is to contact my legal aid and see if I can get out of this situation. Cartrack has the worst service imaginable. Please don't respond to just apologise if you are not resolving my issue, rather you just ignore this review until you have a resolution, I hope this is clear.
